+===LINKJES===
+
+Gegeneerde doxygen kan altijd worden terug gevonden via deze link:
+
+http://koen-github.github.io/TeamHayFaseGame-Delinquent/
+
+
+
+===ALGEMEEN===
+De rapidjson map in de include folder moet worden gekopieerd naar C:\SFML
+De bestanden van Visual Studio .sdf en .openssdf moeten worden genegeerd door github 
+
+De volgende bestanden zijn nodig voor het goed laten fucntioneren van het visual studio project:
+
+- DeDelinquent.sln
+- DeDelinquent.vcxproj
+- DeDelinquent.vcxproj.filters
+
+En verder alle .cpp, .hpp, .h bestanden.
+
+===Regels===
+
+-Header bestanden moeten op .hpp eindigen
+-Gebruik overal pragma once zodat header niet per ongeluk meerdere keren worden geinclude.
+#pragma once
+
+-Geen binaries naar git committen
+
+-Remco neemt altijd zijn nieuwe laptop mee
+-Klassendiagram bijwerken aan de hand van je code, maar dan omgedraait.
+
+-Code in het engels
+-Git commits ook in het engels.
+-Klassen moeten met een Hoofdletter beginnen.
+-Documentaar in het engels
+
+-Volg verder zoveel mogelijk de regeltjes van Wouter die op sharepoint zijn terug te vinden.
+
+===GEBRUIK DOXYGEN===
+
+Gebruik JAVA-DOC style voor het documenteren van de klassen en functies:
+Bijvoorbeeld:
+
+    /**
+       * a normal member taking two arguments and returning an integer value.
+       * @param a an integer argument.
+       * @param s a constant character pointer.
+       * @see Test()
+       * @see ~Test()
+       * @see testMeToo()
+       * @see publicVar()
+       * @return The test results
+       */
+       int testMe(int a,const char *s);
+	  
+-Doxygen wordt soms gegenereerd en vervolgens op de branch gh-pages gezet.

+/// \class sf::SoundBuffer
+/// \ingroup audio
+///
+/// A sound buffer holds the data of a sound, which is
+/// an array of audio samples. A sample is a 16 bits signed integer
+/// that defines the amplitude of the sound at a given time.
+/// The sound is then reconstituted by playing these samples at
+/// a high rate (for example, 44100 samples per second is the
+/// standard rate used for playing CDs). In short, audio samples
+/// are like texture pixels, and a sf::SoundBuffer is similar to
+/// a sf::Texture.
+///
+/// A sound buffer can be loaded from a file (see loadFromFile()
+/// for the complete list of supported formats), from memory, from
+/// a custom stream (see sf::InputStream) or directly from an array
+/// of samples. It can also be saved back to a file.
+///
+/// Sound buffers alone are not very useful: they hold the audio data
+/// but cannot be played. To do so, you need to use the sf::Sound class,
+/// which provides functions to play/pause/stop the sound as well as
+/// changing the way it is outputted (volume, pitch, 3D position, ...).
+/// This separation allows more flexibility and better performances:
+/// indeed a sf::SoundBuffer is a heavy resource, and any operation on it
+/// is slow (often too slow for real-time applications). On the other
+/// side, a sf::Sound is a lightweight object, which can use the audio data
+/// of a sound buffer and change the way it is played without actually
+/// modifying that data. Note that it is also possible to bind
+/// several sf::Sound instances to the same sf::SoundBuffer.
+///
+/// It is important to note that the sf::Sound instance doesn't
+/// copy the buffer that it uses, it only keeps a reference to it.
+/// Thus, a sf::SoundBuffer must not be destructed while it is
+/// used by a sf::Sound (i.e. never write a function that
+/// uses a local sf::SoundBuffer instance for loading a sound).
+///
+/// Usage example:
+/// \code
+/// // Declare a new sound buffer
+/// sf::SoundBuffer buffer;
+///
+/// // Load it from a file
+/// if (!buffer.loadFromFile("sound.wav"))
+/// {
+///     // error...
+/// }
+///
+/// // Create a sound source and bind it to the buffer
+/// sf::Sound sound1;
+/// sound1.setBuffer(buffer);
+///
+/// // Play the sound
+/// sound1.play();
+///
+/// // Create another sound source bound to the same buffer
+/// sf::Sound sound2;
+/// sound2.setBuffer(buffer);
+///
+/// // Play it with a higher pitch -- the first sound remains unchanged
+/// sound2.setPitch(2);
+/// sound2.play();
+/// \endcode
+///
+/// \see sf::Sound, sf::SoundBufferRecorder

+/// \class sf::SoundRecorder
+/// \ingroup audio
+///
+/// sf::SoundBuffer provides a simple interface to access
+/// the audio recording capabilities of the computer
+/// (the microphone). As an abstract base class, it only cares
+/// about capturing sound samples, the task of making something
+/// useful with them is left to the derived class. Note that
+/// SFML provides a built-in specialization for saving the
+/// captured data to a sound buffer (see sf::SoundBufferRecorder).
+///
+/// A derived class has only one virtual function to override:
+/// \li onProcessSamples provides the new chunks of audio samples while the capture happens
+///
+/// Moreover, two additional virtual functions can be overridden
+/// as well if necessary:
+/// \li onStart is called before the capture happens, to perform custom initializations
+/// \li onStop is called after the capture ends, to perform custom cleanup
+///
+/// A derived class can also control the frequency of the onProcessSamples
+/// calls, with the setProcessingInterval protected function. The default
+/// interval is chosen so that recording thread doesn't consume too much
+/// CPU, but it can be changed to a smaller value if you need to process
+/// the recorded data in real time, for example.
+///
+/// The audio capture feature may not be supported or activated
+/// on every platform, thus it is recommended to check its
+/// availability with the isAvailable() function. If it returns
+/// false, then any attempt to use an audio recorder will fail.
+///
+/// If you have multiple sound input devices connected to your
+/// computer (for example: microphone, external soundcard, webcam mic, ...)
+/// you can get a list of all available devices through the
+/// getAvailableDevices() function. You can then select a device
+/// by calling setDevice() with the appropriate device. Otherwise
+/// the default capturing device will be used.
+///
+/// It is important to note that the audio capture happens in a
+/// separate thread, so that it doesn't block the rest of the
+/// program. In particular, the onProcessSamples virtual function
+/// (but not onStart and not onStop) will be called
+/// from this separate thread. It is important to keep this in
+/// mind, because you may have to take care of synchronization
+/// issues if you share data between threads.
+///
+/// Usage example:
+/// \code
+/// class CustomRecorder : public sf::SoundRecorder
+/// {
+///     virtual bool onStart() // optional
+///     {
+///         // Initialize whatever has to be done before the capture starts
+///         ...
+///
+///         // Return true to start playing
+///         return true;
+///     }
+///
+///     virtual bool onProcessSamples(const Int16* samples, std::size_t sampleCount)
+///     {
+///         // Do something with the new chunk of samples (store them, send them, ...)
+///         ...
+///
+///         // Return true to continue playing
+///         return true;
+///     }
+///
+///     virtual void onStop() // optional
+///     {
+///         // Clean up whatever has to be done after the capture ends
+///         ...
+///     }
+/// }
+///
+/// // Usage
+/// if (CustomRecorder::isAvailable())
+/// {
+///     CustomRecorder recorder;
+///
+///     if (!recorder.start())
+///         return -1;
+///
+///     ...
+///     recorder.stop();
+/// }
+/// \endcode

+////////////////////////////////////////////////////////////
+/// \class sf::SoundStream
+/// \ingroup audio
+///
+/// Unlike audio buffers (see sf::SoundBuffer), audio streams
+/// are never completely loaded in memory. Instead, the audio
+/// data is acquired continuously while the stream is playing.
+/// This behavior allows to play a sound with no loading delay,
+/// and keeps the memory consumption very low.
+///
+/// Sound sources that need to be streamed are usually big files
+/// (compressed audio musics that would eat hundreds of MB in memory)
+/// or files that would take a lot of time to be received
+/// (sounds played over the network).
+///
+/// sf::SoundStream is a base class that doesn't care about the
+/// stream source, which is left to the derived class. SFML provides
+/// a built-in specialization for big files (see sf::Music).
+/// No network stream source is provided, but you can write your own
+/// by combining this class with the network module.
+///
+/// A derived class has to override two virtual functions:
+/// \li onGetData fills a new chunk of audio data to be played
+/// \li onSeek changes the current playing position in the source
+///
+/// It is important to note that each SoundStream is played in its
+/// own separate thread, so that the streaming loop doesn't block the
+/// rest of the program. In particular, the OnGetData and OnSeek
+/// virtual functions may sometimes be called from this separate thread.
+/// It is important to keep this in mind, because you may have to take
+/// care of synchronization issues if you share data between threads.
+///
+/// Usage example:
+/// \code
+/// class CustomStream : public sf::SoundStream
+/// {
+/// public:
+///
+///     bool open(const std::string& location)
+///     {
+///         // Open the source and get audio settings
+///         ...
+///         unsigned int channelCount = ...;
+///         unsigned int sampleRate = ...;
+///
+///         // Initialize the stream -- important!
+///         initialize(channelCount, sampleRate);
+///     }
+///
+/// private:
+///
+///     virtual bool onGetData(Chunk& data)
+///     {
+///         // Fill the chunk with audio data from the stream source
+///         // (note: must not be empty if you want to continue playing)
+///         data.samples = ...;
+///         data.sampleCount = ...;
+///
+///         // Return true to continue playing
+///         return true;
+///     }
+///
+///     virtual void onSeek(Uint32 timeOffset)
+///     {
+///         // Change the current position in the stream source
+///         ...
+///     }
+/// }
+///
+/// // Usage
+/// CustomStream stream;
+/// stream.open("path/to/stream");
+/// stream.play();
+/// \endcode

+/// \class sf::BlendMode
+/// \ingroup graphics
+///
+/// sf::BlendMode is a class that represents a blend mode. A blend
+/// mode determines how the colors of an object you draw are
+/// mixed with the colors that are already in the buffer.
+///
+/// The class is composed of 6 components, each of which has its
+/// own public member variable:
+/// \li %Color Source Factor (@ref colorSrcFactor)
+/// \li %Color Destination Factor (@ref colorDstFactor)
+/// \li %Color Blend Equation (@ref colorEquation)
+/// \li Alpha Source Factor (@ref alphaSrcFactor)
+/// \li Alpha Destination Factor (@ref alphaDstFactor)
+/// \li Alpha Blend Equation (@ref alphaEquation)
+///
+/// The source factor specifies how the pixel you are drawing contributes
+/// to the final color. The destination factor specifies how the pixel
+/// already drawn in the buffer contributes to the final color.
+///
+/// The color channels RGB (red, green, blue; simply referred to as
+/// color) and A (alpha; the transparency) can be treated separately. This
+/// separation can be useful for specific blend modes, but most often you
+/// won't need it and will simply treat the color as a single unit.
+///
+/// The blend factors and equations correspond to their OpenGL equivalents.
+/// In general, the color of the resulting pixel is calculated according
+/// to the following formula (\a src is the color of the source pixel, \a dst
+/// the color of the destination pixel, the other variables correspond to the
+/// public members, with the equations being + or - operators):
+/// \code
+/// dst.rgb = colorSrcFactor * src.rgb (colorEquation) colorDstFactor * dst.rgb
+/// dst.a   = alphaSrcFactor * src.a   (alphaEquation) alphaDstFactor * dst.a
+/// \endcode
+/// All factors and colors are represented as floating point numbers between
+/// 0 and 1. Where necessary, the result is clamped to fit in that range.
+///
+/// The most common blending modes are defined as constants
+/// in the sf namespace:
+///
+/// \code
+/// sf::BlendMode alphaBlending          = sf::BlendAlpha;
+/// sf::BlendMode additiveBlending       = sf::BlendAdd;
+/// sf::BlendMode multiplicativeBlending = sf::BlendMultipy;
+/// sf::BlendMode noBlending             = sf::BlendNone;
+/// \endcode
+///
+/// In SFML, a blend mode can be specified every time you draw a sf::Drawable
+/// object to a render target. It is part of the sf::RenderStates compound
+/// that is passed to the member function sf::RenderTarget::draw().
+///
+/// \see sf::RenderStates, sf::RenderTarget

+/// sf::Color is a simple color class composed of 4 components:
+/// \li Red
+/// \li Green
+/// \li Blue
+/// \li Alpha (opacity)
+///
+/// Each component is a public member, an unsigned integer in
+/// the range [0, 255]. Thus, colors can be constructed and
+/// manipulated very easily:
+///
+/// \code
+/// sf::Color color(255, 0, 0); // red
+/// color.r = 0;                // make it black
+/// color.b = 128;              // make it dark blue
+/// \endcode
+///
+/// The fourth component of colors, named "alpha", represents
+/// the opacity of the color. A color with an alpha value of
+/// 255 will be fully opaque, while an alpha value of 0 will
+/// make a color fully transparent, whatever the value of the
+/// other components is.
+///
+/// The most common colors are already defined as static variables:
+/// \code
+/// sf::Color black       = sf::Color::Black;
+/// sf::Color white       = sf::Color::White;
+/// sf::Color red         = sf::Color::Red;

+/// sf::Color magenta     = sf::Color::Magenta;
+/// sf::Color cyan        = sf::Color::Cyan;
+/// sf::Color transparent = sf::Color::Transparent;
+/// \endcode
+///
+/// Colors can also be added and modulated (multiplied) using the
+/// overloaded operators + and *.

+/// \class sf::Font
+/// \ingroup graphics
+///
+/// Fonts can be loaded from a file, from memory or from a custom
+/// stream, and supports the most common types of fonts. See
+/// the loadFromFile function for the complete list of supported formats.
+///
+/// Once it is loaded, a sf::Font instance provides three
+/// types of information about the font:
+/// \li Global metrics, such as the line spacing
+/// \li Per-glyph metrics, such as bounding box or kerning
+/// \li Pixel representation of glyphs
+///
+/// Fonts alone are not very useful: they hold the font data
+/// but cannot make anything useful of it. To do so you need to
+/// use the sf::Text class, which is able to properly output text
+/// with several options such as character size, style, color,
+/// position, rotation, etc.
+/// This separation allows more flexibility and better performances:
+/// indeed a sf::Font is a heavy resource, and any operation on it
+/// is slow (often too slow for real-time applications). On the other
+/// side, a sf::Text is a lightweight object which can combine the
+/// glyphs data and metrics of a sf::Font to display any text on a
+/// render target.
+/// Note that it is also possible to bind several sf::Text instances
+/// to the same sf::Font.
+///
+/// It is important to note that the sf::Text instance doesn't
+/// copy the font that it uses, it only keeps a reference to it.
+/// Thus, a sf::Font must not be destructed while it is
+/// used by a sf::Text (i.e. never write a function that
+/// uses a local sf::Font instance for creating a text).
+///
+/// Usage example:
+/// \code
+/// // Declare a new font
+/// sf::Font font;
+///
+/// // Load it from a file
+/// if (!font.loadFromFile("arial.ttf"))
+/// {
+///     // error...
+/// }
+///
+/// // Create a text which uses our font
+/// sf::Text text1;
+/// text1.setFont(font);
+/// text1.setCharacterSize(30);
+/// text1.setStyle(sf::Text::Regular);
+///
+/// // Create another text using the same font, but with different parameters
+/// sf::Text text2;
+/// text2.setFont(font);
+/// text2.setCharacterSize(50);
+/// text1.setStyle(sf::Text::Italic);
+/// \endcode
+///
+/// Apart from loading font files, and passing them to instances
+/// of sf::Text, you should normally not have to deal directly
+/// with this class. However, it may be useful to access the
+/// font metrics or rasterized glyphs for advanced usage.
+///
+/// Note that if the font is a bitmap font, it is not scalable,
+/// thus not all requested sizes will be available to use. This
+/// needs to be taken into consideration when using sf::Text.
+/// If you need to display text of a certain size, make sure the
+/// corresponding bitmap font that supports that size is used.
+///
+/// \see sf::Text

+/// \class sf::Image
+/// \ingroup graphics
+///
+/// sf::Image is an abstraction to manipulate images
+/// as bidimensional arrays of pixels. The class provides
+/// functions to load, read, write and save pixels, as well
+/// as many other useful functions.
+///
+/// sf::Image can handle a unique internal representation of
+/// pixels, which is RGBA 32 bits. This means that a pixel
+/// must be composed of 8 bits red, green, blue and alpha
+/// channels -- just like a sf::Color.
+/// All the functions that return an array of pixels follow
+/// this rule, and all parameters that you pass to sf::Image
+/// functions (such as loadFromMemory) must use this
+/// representation as well.
+///
+/// A sf::Image can be copied, but it is a heavy resource and
+/// if possible you should always use [const] references to
+/// pass or return them to avoid useless copies.
+///
+/// Usage example:
+/// \code
+/// // Load an image file from a file
+/// sf::Image background;
+/// if (!background.loadFromFile("background.jpg"))
+///     return -1;
+///
+/// // Create a 20x20 image filled with black color
+/// sf::Image image;
+/// image.create(20, 20, sf::Color::Black);
+///
+/// // Copy image1 on image2 at position (10, 10)
+/// image.copy(background, 10, 10);
+///
+/// // Make the top-left pixel transparent
+/// sf::Color color = image.getPixel(0, 0);
+/// color.a = 0;
+/// image.setPixel(0, 0, color);
+///
+/// // Save the image to a file
+/// if (!image.saveToFile("result.png"))
+///     return -1;
+/// \endcode
+///

+/// \class sf::Rect
+/// \ingroup graphics
+///
+/// A rectangle is defined by its top-left corner and its size.
+/// It is a very simple class defined for convenience, so
+/// its member variables (left, top, width and height) are public
+/// and can be accessed directly, just like the vector classes
+/// (Vector2 and Vector3).
+///
+/// To keep things simple, sf::Rect doesn't define
+/// functions to emulate the properties that are not directly
+/// members (such as right, bottom, center, etc.), it rather
+/// only provides intersection functions.
+///
+/// sf::Rect uses the usual rules for its boundaries:
+/// \li The left and top edges are included in the rectangle's area
+/// \li The right (left + width) and bottom (top + height) edges are excluded from the rectangle's area
+///
+/// This means that sf::IntRect(0, 0, 1, 1) and sf::IntRect(1, 1, 1, 1)
+/// don't intersect.
+///
+/// sf::Rect is a template and may be used with any numeric type, but
+/// for simplicity the instantiations used by SFML are typedef'd:
+/// \li sf::Rect<int> is sf::IntRect
+/// \li sf::Rect<float> is sf::FloatRect
+///
+/// So that you don't have to care about the template syntax.
+///
+/// Usage example:
+/// \code
+/// // Define a rectangle, located at (0, 0) with a size of 20x5
+/// sf::IntRect r1(0, 0, 20, 5);
+///
+/// // Define another rectangle, located at (4, 2) with a size of 18x10
+/// sf::Vector2i position(4, 2);
+/// sf::Vector2i size(18, 10);
+/// sf::IntRect r2(position, size);
+///
+/// // Test intersections with the point (3, 1)
+/// bool b1 = r1.contains(3, 1); // true
+/// bool b2 = r2.contains(3, 1); // false
+///
+/// // Test the intersection between r1 and r2
+/// sf::IntRect result;
+/// bool b3 = r1.intersects(r2, result); // true
+/// // result == (4, 2, 16, 3)
+/// \endcode

+/// \li the transform: how the object is positioned/rotated/scaled
+/// \li the texture: what image is mapped to the object
+/// \li the shader: what custom effect is applied to the object
+///
+/// High-level objects such as sprites or text force some of
+/// these states when they are drawn. For example, a sprite
+/// will set its own texture, so that you don't have to care
+/// about it when drawing the sprite.
+///
+/// The transform is a special case: sprites, texts and shapes
+/// (and it's a good idea to do it with your own drawable classes
+/// too) combine their transform with the one that is passed in the
+/// RenderStates structure. So that you can use a "global" transform
+/// on top of each object's transform.
+///
+/// Most objects, especially high-level drawables, can be drawn
+/// directly without defining render states explicitly -- the
+/// default set of states is ok in most cases.
+/// \code
+/// window.draw(sprite);
+/// \endcode
+///
+/// If you want to use a single specific render state,
+/// for example a shader, you can pass it directly to the Draw
+/// function: sf::RenderStates has an implicit one-argument
+/// constructor for each state.
+/// \code
+/// window.draw(sprite, shader);
+/// \endcode
+///
+/// When you're inside the Draw function of a drawable
+/// object (inherited from sf::Drawable), you can
+/// either pass the render states unmodified, or change
+/// some of them.
+/// For example, a transformable object will combine the
+/// current transform with its own transform. A sprite will
+/// set its texture. Etc.

+///
+/// Rendering to a texture can be useful in a variety of situations:

+/// \li creating a sprite from a 3D object rendered with OpenGL
+/// \li etc.
+///
+/// Usage example:
+///
+/// \code
+/// // Create a new render-window
+/// sf::RenderWindow window(sf::VideoMode(800, 600), "SFML window");
+///
+/// // Create a new render-texture

+///     return -1;
+///
+/// // The main loop

+///    // ...
+///
+///    // Clear the whole texture with red color

+///
+///    // Draw stuff to the texture
+///    texture.draw(sprite);  // sprite is a sf::Sprite
+///    texture.draw(shape);   // shape is a sf::Shape
+///    texture.draw(text);    // text is a sf::Text
+///
+///    // We're done drawing to the texture
+///    texture.display();
+///
+///    // Now we start rendering to the window, clear it first

+///
+///    // Draw the texture

+///    window.draw(sprite);
+///
+///    // End the current frame and display its contents on screen

+/// \endcode
+///
+/// Like sf::RenderWindow, sf::RenderTexture is still able to render direct

+/// \class sf::Shader
+/// \ingroup graphics
+///
+/// Shaders are programs written using a specific language,
+/// executed directly by the graphics card and allowing
+/// to apply real-time operations to the rendered entities.
+///
+/// There are two kinds of shaders:
+/// \li Vertex shaders, that process vertices
+/// \li Fragment (pixel) shaders, that process pixels
+///
+/// A sf::Shader can be composed of either a vertex shader
+/// alone, a fragment shader alone, or both combined
+/// (see the variants of the load functions).
+///
+/// Shaders are written in GLSL, which is a C-like
+/// language dedicated to OpenGL shaders. You'll probably
+/// need to learn its basics before writing your own shaders
+/// for SFML.
+///
+/// Like any C/C++ program, a shader has its own variables
+/// that you can set from your C++ application. sf::Shader
+/// handles 5 different types of variables:
+/// \li floats
+/// \li vectors (2, 3 or 4 components)
+/// \li colors
+/// \li textures
+/// \li transforms (matrices)
+///
+/// The value of the variables can be changed at any time
+/// with the various overloads of the setParameter function:
+/// \code
+/// shader.setParameter("offset", 2.f);
+/// shader.setParameter("point", 0.5f, 0.8f, 0.3f);
+/// shader.setParameter("color", sf::Color(128, 50, 255));
+/// shader.setParameter("matrix", transform); // transform is a sf::Transform
+/// shader.setParameter("overlay", texture); // texture is a sf::Texture
+/// shader.setParameter("texture", sf::Shader::CurrentTexture);
+/// \endcode
+///
+/// The special Shader::CurrentTexture argument maps the
+/// given texture variable to the current texture of the
+/// object being drawn (which cannot be known in advance).
+///
+/// To apply a shader to a drawable, you must pass it as an
+/// additional parameter to the Draw function:
+/// \code
+/// window.draw(sprite, &shader);
+/// \endcode
+///
+/// ... which is in fact just a shortcut for this:
+/// \code
+/// sf::RenderStates states;
+/// states.shader = &shader;
+/// window.draw(sprite, states);
+/// \endcode
+///
+/// In the code above we pass a pointer to the shader, because it may
+/// be null (which means "no shader").
+///
+/// Shaders can be used on any drawable, but some combinations are
+/// not interesting. For example, using a vertex shader on a sf::Sprite
+/// is limited because there are only 4 vertices, the sprite would
+/// have to be subdivided in order to apply wave effects.
+/// Another bad example is a fragment shader with sf::Text: the texture
+/// of the text is not the actual text that you see on screen, it is
+/// a big texture containing all the characters of the font in an
+/// arbitrary order; thus, texture lookups on pixels other than the
+/// current one may not give you the expected result.
+///
+/// Shaders can also be used to apply global post-effects to the
+/// current contents of the target (like the old sf::PostFx class
+/// in SFML 1). This can be done in two different ways:
+/// \li draw everything to a sf::RenderTexture, then draw it to
+///     the main target using the shader
+/// \li draw everything directly to the main target, then use
+///     sf::Texture::update(Window&) to copy its contents to a texture
+///     and draw it to the main target using the shader
+///
+/// The first technique is more optimized because it doesn't involve
+/// retrieving the target's pixels to system memory, but the
+/// second one doesn't impact the rendering process and can be
+/// easily inserted anywhere without impacting all the code.
+///
+/// Like sf::Texture that can be used as a raw OpenGL texture,
+/// sf::Shader can also be used directly as a raw shader for
+/// custom OpenGL geometry.
+/// \code
+/// sf::Shader::bind(&shader);
+/// ... render OpenGL geometry ...
+/// sf::Shader::bind(NULL);
+/// \endcode

+/// \class sf::Sprite
+/// \ingroup graphics
+///
+/// sf::Sprite is a drawable class that allows to easily display
+/// a texture (or a part of it) on a render target.
+///
+/// It inherits all the functions from sf::Transformable:
+/// position, rotation, scale, origin. It also adds sprite-specific
+/// properties such as the texture to use, the part of it to display,
+/// and some convenience functions to change the overall color of the
+/// sprite, or to get its bounding rectangle.
+///
+/// sf::Sprite works in combination with the sf::Texture class, which
+/// loads and provides the pixel data of a given texture.
+///
+/// The separation of sf::Sprite and sf::Texture allows more flexibility
+/// and better performances: indeed a sf::Texture is a heavy resource,
+/// and any operation on it is slow (often too slow for real-time
+/// applications). On the other side, a sf::Sprite is a lightweight
+/// object which can use the pixel data of a sf::Texture and draw
+/// it with its own transformation/color/blending attributes.
+///
+/// It is important to note that the sf::Sprite instance doesn't
+/// copy the texture that it uses, it only keeps a reference to it.
+/// Thus, a sf::Texture must not be destroyed while it is
+/// used by a sf::Sprite (i.e. never write a function that
+/// uses a local sf::Texture instance for creating a sprite).
+///
+/// See also the note on coordinates and undistorted rendering in sf::Transformable.
+///
+/// Usage example:
+/// \code
+/// // Declare and load a texture
+/// sf::Texture texture;
+/// texture.loadFromFile("texture.png");
+///
+/// // Create a sprite
+/// sf::Sprite sprite;
+/// sprite.setTexture(texture);
+/// sprite.setTextureRect(sf::IntRect(10, 10, 50, 30));
+/// sprite.setColor(sf::Color(255, 255, 255, 200));

+////////////////////////////////////////////////////////////
+/// \class sf::Text
+/// \ingroup graphics
+///
+/// sf::Text is a drawable class that allows to easily display
+/// some text with custom style and color on a render target.
+///
+/// It inherits all the functions from sf::Transformable:
+/// position, rotation, scale, origin. It also adds text-specific
+/// properties such as the font to use, the character size,
+/// the font style (bold, italic, underlined, strike through), the
+/// global color and the text to display of course.
+/// It also provides convenience functions to calculate the
+/// graphical size of the text, or to get the global position
+/// of a given character.
+///
+/// sf::Text works in combination with the sf::Font class, which
+/// loads and provides the glyphs (visual characters) of a given font.
+///
+/// The separation of sf::Font and sf::Text allows more flexibility
+/// and better performances: indeed a sf::Font is a heavy resource,
+/// and any operation on it is slow (often too slow for real-time
+/// applications). On the other side, a sf::Text is a lightweight
+/// object which can combine the glyphs data and metrics of a sf::Font
+/// to display any text on a render target.
+///
+/// It is important to note that the sf::Text instance doesn't
+/// copy the font that it uses, it only keeps a reference to it.
+/// Thus, a sf::Font must not be destructed while it is
+/// used by a sf::Text (i.e. never write a function that
+/// uses a local sf::Font instance for creating a text).
+///
+/// See also the note on coordinates and undistorted rendering in sf::Transformable.
+///
+/// Usage example:
+/// \code
+/// // Declare and load a font
+/// sf::Font font;
+/// font.loadFromFile("arial.ttf");
+///
+/// // Create a text
+/// sf::Text text("hello", font);
+/// text.setCharacterSize(30);
+/// text.setStyle(sf::Text::Bold);
+/// text.setColor(sf::Color::Red);
+///
+/// // Draw it
+/// window.draw(text);
+/// \endcode
+///
+/// \see sf::Font, sf::Transformable

+////////////////////////////////////////////////////////////
+/// \class sf::Texture
+/// \ingroup graphics
+///
+/// sf::Texture stores pixels that can be drawn, with a sprite
+/// for example. A texture lives in the graphics card memory,
+/// therefore it is very fast to draw a texture to a render target,
+/// or copy a render target to a texture (the graphics card can
+/// access both directly).
+///
+/// Being stored in the graphics card memory has some drawbacks.
+/// A texture cannot be manipulated as freely as a sf::Image,
+/// you need to prepare the pixels first and then upload them
+/// to the texture in a single operation (see Texture::update).
+///
+/// sf::Texture makes it easy to convert from/to sf::Image, but
+/// keep in mind that these calls require transfers between
+/// the graphics card and the central memory, therefore they are
+/// slow operations.
+///
+/// A texture can be loaded from an image, but also directly
+/// from a file/memory/stream. The necessary shortcuts are defined
+/// so that you don't need an image first for the most common cases.
+/// However, if you want to perform some modifications on the pixels
+/// before creating the final texture, you can load your file to a
+/// sf::Image, do whatever you need with the pixels, and then call
+/// Texture::loadFromImage.
+///
+/// Since they live in the graphics card memory, the pixels of a texture
+/// cannot be accessed without a slow copy first. And they cannot be
+/// accessed individually. Therefore, if you need to read the texture's
+/// pixels (like for pixel-perfect collisions), it is recommended to
+/// store the collision information separately, for example in an array
+/// of booleans.
+///
+/// Like sf::Image, sf::Texture can handle a unique internal
+/// representation of pixels, which is RGBA 32 bits. This means
+/// that a pixel must be composed of 8 bits red, green, blue and
+/// alpha channels -- just like a sf::Color.
+///
+/// Usage example:
+/// \code
+/// // This example shows the most common use of sf::Texture:
+/// // drawing a sprite
+///
+/// // Load a texture from a file
+/// sf::Texture texture;
+/// if (!texture.loadFromFile("texture.png"))
+///     return -1;
+///
+/// // Assign it to a sprite
+/// sf::Sprite sprite;
+/// sprite.setTexture(texture);
+///
+/// // Draw the textured sprite
+/// window.draw(sprite);
+/// \endcode
+///
+/// \code
+/// // This example shows another common use of sf::Texture:
+/// // streaming real-time data, like video frames
+///
+/// // Create an empty texture
+/// sf::Texture texture;
+/// if (!texture.create(640, 480))
+///     return -1;
+///
+/// // Create a sprite that will display the texture
+/// sf::Sprite sprite(texture);
+///
+/// while (...) // the main loop
+/// {
+///     ...
+///
+///     // update the texture
+///     sf::Uint8* pixels = ...; // get a fresh chunk of pixels (the next frame of a movie, for example)
+///     texture.update(pixels);
+///
+///     // draw it
+///     window.draw(sprite);
+///
+///     ...
+/// }
+///
+/// \endcode
+///
+/// Like sf::Shader that can be used as a raw OpenGL shader,
+/// sf::Texture can also be used directly as a raw texture for
+/// custom OpenGL geometry.
+/// \code
+/// sf::Texture::bind(&texture);
+/// ... render OpenGL geometry ...
+/// sf::Texture::bind(NULL);
+/// \endcode
+///
+/// \see sf::Sprite, sf::Image, sf::RenderTexture

+/// A sf::Transform specifies how to translate, rotate, scale,
+/// shear, project, whatever things. In mathematical terms, it defines
+/// how to transform a coordinate system into another.
+///
+/// For example, if you apply a rotation transform to a sprite, the
+/// result will be a rotated sprite. And anything that is transformed
+/// by this rotation transform will be rotated the same way, according
+/// to its initial position.
+///
+/// Transforms are typically used for drawing. But they can also be
+/// used for any computation that requires to transform points between
+/// the local and global coordinate systems of an entity (like collision
+/// detection).
+///
+/// Example:
+/// \code
+/// // define a translation transform
+/// sf::Transform translation;
+/// translation.translate(20, 50);
+///
+/// // define a rotation transform
+/// sf::Transform rotation;
+/// rotation.rotate(45);
+///
+/// // combine them
+/// sf::Transform transform = translation * rotation;
+///
+/// // use the result to transform stuff...
+/// sf::Vector2f point = transform.transformPoint(10, 20);
+/// sf::FloatRect rect = transform.transformRect(sf::FloatRect(0, 0, 10, 100));

+/// \class sf::Transformable
+/// \ingroup graphics
+///
+/// This class is provided for convenience, on top of sf::Transform.
+///
+/// sf::Transform, as a low-level class, offers a great level of
+/// flexibility but it is not always convenient to manage. Indeed,
+/// one can easily combine any kind of operation, such as a translation
+/// followed by a rotation followed by a scaling, but once the result
+/// transform is built, there's no way to go backward and, let's say,
+/// change only the rotation without modifying the translation and scaling.
+/// The entire transform must be recomputed, which means that you
+/// need to retrieve the initial translation and scale factors as
+/// well, and combine them the same way you did before updating the
+/// rotation. This is a tedious operation, and it requires to store
+/// all the individual components of the final transform.
+///
+/// That's exactly what sf::Transformable was written for: it hides
+/// these variables and the composed transform behind an easy to use
+/// interface. You can set or get any of the individual components
+/// without worrying about the others. It also provides the composed
+/// transform (as a sf::Transform), and keeps it up-to-date.
+///
+/// In addition to the position, rotation and scale, sf::Transformable
+/// provides an "origin" component, which represents the local origin
+/// of the three other components. Let's take an example with a 10x10
+/// pixels sprite. By default, the sprite is positioned/rotated/scaled
+/// relatively to its top-left corner, because it is the local point
+/// (0, 0). But if we change the origin to be (5, 5), the sprite will
+/// be positioned/rotated/scaled around its center instead. And if
+/// we set the origin to (10, 10), it will be transformed around its
+/// bottom-right corner.
+///
+/// To keep the sf::Transformable class simple, there's only one
+/// origin for all the components. You cannot position the sprite
+/// relatively to its top-left corner while rotating it around its
+/// center, for example. To do such things, use sf::Transform directly.
+///
+/// sf::Transformable can be used as a base class. It is often
+/// combined with sf::Drawable -- that's what SFML's sprites,
+/// texts and shapes do.
+/// \code
+/// class MyEntity : public sf::Transformable, public sf::Drawable
+/// {
+///     virtual void draw(sf::RenderTarget& target, sf::RenderStates states) const
+///     {
+///         states.transform *= getTransform();
+///         target.draw(..., states);
+///     }
+/// };
+///
+/// MyEntity entity;
+/// entity.setPosition(10, 20);
+/// entity.setRotation(45);
+/// window.draw(entity);
+/// \endcode
+///
+/// It can also be used as a member, if you don't want to use
+/// its API directly (because you don't need all its functions,
+/// or you have different naming conventions for example).
+/// \code
+/// class MyEntity
+/// {
+/// public:
+///     void SetPosition(const MyVector& v)
+///     {
+///         myTransform.setPosition(v.x(), v.y());
+///     }
+///
+///     void Draw(sf::RenderTarget& target) const
+///     {
+///         target.draw(..., myTransform.getTransform());
+///     }
+///
+/// private:
+///     sf::Transformable myTransform;
+/// };
+/// \endcode
+///
+/// A note on coordinates and undistorted rendering: \n
+/// By default, SFML (or more exactly, OpenGL) may interpolate drawable objects
+/// such as sprites or texts when rendering. While this allows transitions
+/// like slow movements or rotations to appear smoothly, it can lead to
+/// unwanted results in some cases, for example blurred or distorted objects.
+/// In order to render a sf::Drawable object pixel-perfectly, make sure
+/// the involved coordinates allow a 1:1 mapping of pixels in the window
+/// to texels (pixels in the texture). More specifically, this means:
+/// * The object's position, origin and scale have no fractional part
+/// * The object's and the view's rotation are a multiple of 90 degrees
+/// * The view's center and size have no fractional part
+///
+/// \see sf::Transform

+/// A vertex is an improved point. It has a position and other

+/// The vertex is the building block of drawing. Everything which

+/// you won't have to deal with vertices directly. But if you want

+/// systems, using vertices will allow you to get maximum performances.

+///
+/// sf::View defines a camera in the 2D scene. This is a
+/// very powerful concept: you can scroll, rotate or zoom
+/// the entire scene without altering the way that your
+/// drawable objects are drawn.
+///
+/// A view is composed of a source rectangle, which defines
+/// what part of the 2D scene is shown, and a target viewport,
+/// which defines where the contents of the source rectangle
+/// will be displayed on the render target (window or texture).
+///
+/// The viewport allows to map the scene to a custom part
+/// of the render target, and can be used for split-screen
+/// or for displaying a minimap, for example. If the source
+/// rectangle has not the same size as the viewport, its
+/// contents will be stretched to fit in.
+///
+/// To apply a view, you have to assign it to the render target.
+/// Then, every objects drawn in this render target will be
+/// affected by the view until you use another view.
+///
+/// Usage example:
+/// \code
+/// sf::RenderWindow window;
+/// sf::View view;
+///
+/// // Initialize the view to a rectangle located at (100, 100) and with a size of 400x200
+/// view.reset(sf::FloatRect(100, 100, 400, 200));
+///
+/// // Rotate it by 45 degrees
+/// view.rotate(45);
+///
+/// // Set its target viewport to be half of the window
+/// view.setViewport(sf::FloatRect(0.f, 0.f, 0.5f, 1.f));
+///
+/// // Apply it
+/// window.setView(view);
+///
+/// // Render stuff
+/// window.draw(someSprite);
+///
+/// // Set the default view back
+/// window.setView(window.getDefaultView());
+///
+/// // Render stuff not affected by the view
+/// window.draw(someText);
+/// \endcode
+///
+/// See also the note on coordinates and undistorted rendering in sf::Transformable.

+////////////////////////////////////////////////////////////
+/// \class sf::Ftp
+/// \ingroup network
+///
+/// sf::Ftp is a very simple FTP client that allows you
+/// to communicate with a FTP server. The FTP protocol allows
+/// you to manipulate a remote file system (list files,
+/// upload, download, create, remove, ...).
+///
+/// Using the FTP client consists of 4 parts:
+/// \li Connecting to the FTP server
+/// \li Logging in (either as a registered user or anonymously)
+/// \li Sending commands to the server
+/// \li Disconnecting (this part can be done implicitly by the destructor)
+///
+/// Every command returns a FTP response, which contains the
+/// status code as well as a message from the server. Some
+/// commands such as getWorkingDirectory() and getDirectoryListing()
+/// return additional data, and use a class derived from
+/// sf::Ftp::Response to provide this data. The most often used
+/// commands are directly provided as member functions, but it is
+/// also possible to use specific commands with the sendCommand() function.
+///
+/// Note that response statuses >= 1000 are not part of the FTP standard,
+/// they are generated by SFML when an internal error occurs.
+///
+/// All commands, especially upload and download, may take some
+/// time to complete. This is important to know if you don't want
+/// to block your application while the server is completing
+/// the task.
+///
+/// Usage example:
+/// \code
+/// // Create a new FTP client
+/// sf::Ftp ftp;
+///
+/// // Connect to the server
+/// sf::Ftp::Response response = ftp.connect("ftp://ftp.myserver.com");
+/// if (response.isOk())
+///     std::cout << "Connected" << std::endl;
+///
+/// // Log in
+/// response = ftp.login("laurent", "dF6Zm89D");
+/// if (response.isOk())
+///     std::cout << "Logged in" << std::endl;
+///
+/// // Print the working directory
+/// sf::Ftp::DirectoryResponse directory = ftp.getWorkingDirectory();
+/// if (directory.isOk())
+///     std::cout << "Working directory: " << directory.getDirectory() << std::endl;
+///
+/// // Create a new directory
+/// response = ftp.createDirectory("files");
+/// if (response.isOk())
+///     std::cout << "Created new directory" << std::endl;
+///
+/// // Upload a file to this new directory
+/// response = ftp.upload("local-path/file.txt", "files", sf::Ftp::Ascii);
+/// if (response.isOk())
+///     std::cout << "File uploaded" << std::endl;
+///
+/// // Send specific commands (here: FEAT to list supported FTP features)
+/// response = ftp.sendCommand("FEAT");
+/// if (response.isOk())
+///     std::cout << "Feature list:\n" << response.getMessage() << std::endl;
+///
+/// // Disconnect from the server (optional)
+/// ftp.disconnect();
+/// \endcode

+/// \class sf::Http
+/// \ingroup network
+///
+/// sf::Http is a very simple HTTP client that allows you
+/// to communicate with a web server. You can retrieve
+/// web pages, send data to an interactive resource,
+/// download a remote file, etc. The HTTPS protocol is
+/// not supported.
+///
+/// The HTTP client is split into 3 classes:
+/// \li sf::Http::Request
+/// \li sf::Http::Response
+/// \li sf::Http
+///
+/// sf::Http::Request builds the request that will be
+/// sent to the server. A request is made of:
+/// \li a method (what you want to do)
+/// \li a target URI (usually the name of the web page or file)
+/// \li one or more header fields (options that you can pass to the server)
+/// \li an optional body (for POST requests)
+///
+/// sf::Http::Response parse the response from the web server
+/// and provides getters to read them. The response contains:
+/// \li a status code
+/// \li header fields (that may be answers to the ones that you requested)
+/// \li a body, which contains the contents of the requested resource
+///
+/// sf::Http provides a simple function, SendRequest, to send a
+/// sf::Http::Request and return the corresponding sf::Http::Response
+/// from the server.
+///
+/// Usage example:
+/// \code
+/// // Create a new HTTP client
+/// sf::Http http;
+///
+/// // We'll work on http://www.sfml-dev.org
+/// http.setHost("http://www.sfml-dev.org");
+///
+/// // Prepare a request to get the 'features.php' page
+/// sf::Http::Request request("features.php");
+///
+/// // Send the request
+/// sf::Http::Response response = http.sendRequest(request);
+///
+/// // Check the status code and display the result
+/// sf::Http::Response::Status status = response.getStatus();
+/// if (status == sf::Http::Response::Ok)
+/// {
+///     std::cout << response.getBody() << std::endl;
+/// }
+/// else
+/// {
+///     std::cout << "Error " << status << std::endl;
+/// }
+/// \endcode

+/// \class sf::Packet
+/// \ingroup network
+///
+/// Packets provide a safe and easy way to serialize data,
+/// in order to send it over the network using sockets
+/// (sf::TcpSocket, sf::UdpSocket).
+///
+/// Packets solve 2 fundamental problems that arise when
+/// transferring data over the network:
+/// \li data is interpreted correctly according to the endianness
+/// \li the bounds of the packet are preserved (one send == one receive)
+///
+/// The sf::Packet class provides both input and output modes.
+/// It is designed to follow the behavior of standard C++ streams,
+/// using operators >> and << to extract and insert data.
+///
+/// It is recommended to use only fixed-size types (like sf::Int32, etc.),
+/// to avoid possible differences between the sender and the receiver.
+/// Indeed, the native C++ types may have different sizes on two platforms
+/// and your data may be corrupted if that happens.
+///
+/// Usage example:
+/// \code
+/// sf::Uint32 x = 24;
+/// std::string s = "hello";
+/// double d = 5.89;
+///
+/// // Group the variables to send into a packet
+/// sf::Packet packet;
+/// packet << x << s << d;
+///
+/// // Send it over the network (socket is a valid sf::TcpSocket)
+/// socket.send(packet);
+///
+/// -----------------------------------------------------------------
+///
+/// // Receive the packet at the other end
+/// sf::Packet packet;
+/// socket.receive(packet);
+///
+/// // Extract the variables contained in the packet
+/// sf::Uint32 x;
+/// std::string s;
+/// double d;
+/// if (packet >> x >> s >> d)
+/// {
+///     // Data extracted successfully...
+/// }
+/// \endcode
+///
+/// Packets have built-in operator >> and << overloads for
+/// standard types:
+/// \li bool
+/// \li fixed-size integer types (sf::Int8/16/32, sf::Uint8/16/32)
+/// \li floating point numbers (float, double)
+/// \li string types (char*, wchar_t*, std::string, std::wstring, sf::String)
+///
+/// Like standard streams, it is also possible to define your own
+/// overloads of operators >> and << in order to handle your
+/// custom types.
+///
+/// \code
+/// struct MyStruct
+/// {
+///     float       number;
+///     sf::Int8    integer;
+///     std::string str;
+/// };
+///
+/// sf::Packet& operator <<(sf::Packet& packet, const MyStruct& m)
+/// {
+///     return packet << m.number << m.integer << m.str;
+/// }
+///
+/// sf::Packet& operator >>(sf::Packet& packet, MyStruct& m)
+/// {
+///     return packet >> m.number >> m.integer >> m.str;
+/// }
+/// \endcode
+///
+/// Packets also provide an extra feature that allows to apply
+/// custom transformations to the data before it is sent,
+/// and after it is received. This is typically used to

+/// \class sf::Socket
+/// \ingroup network
+///
+/// This class mainly defines internal stuff to be used by
+/// derived classes.
+///
+/// The only public features that it defines, and which
+/// is therefore common to all the socket classes, is the
+/// blocking state. All sockets can be set as blocking or
+/// non-blocking.
+///
+/// In blocking mode, socket functions will hang until
+/// the operation completes, which means that the entire
+/// program (well, in fact the current thread if you use
+/// multiple ones) will be stuck waiting for your socket
+/// operation to complete.
+///
+/// In non-blocking mode, all the socket functions will
+/// return immediately. If the socket is not ready to complete
+/// the requested operation, the function simply returns
+/// the proper status code (Socket::NotReady).
+///
+/// The default mode, which is blocking, is the one that is
+/// generally used, in combination with threads or selectors.
+/// The non-blocking mode is rather used in real-time
+/// applications that run an endless loop that can poll
+/// the socket often enough, and cannot afford blocking
+/// this loop.
