/// \class sf::RenderTexture
/// \ingroup graphics
///
/// sf::RenderTexture is the little brother of sf::RenderWindow.
/// It implements the same 2D drawing and OpenGL-related functions
/// (see their base class sf::RenderTarget for more details),
/// the difference is that the result is stored in an off-screen
/// texture rather than being show in a window.
///
/// Rendering to a texture can be useful in a variety of situations:
/// \li precomputing a complex static texture (like a level's background from multiple tiles)
/// \li applying post-effects to the whole scene with shaders
/// \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
/// sf::RenderTexture texture;
/// if (!texture.create(500, 500))
/// return -1;
///
/// // The main loop
/// while (window.isOpen())
/// {
/// // Event processing
/// // ...
///
/// // Clear the whole texture with red color
/// texture.clear(sf::Color::Red);
///
/// // 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
/// window.clear();
///
/// // Draw the texture
/// sf::Sprite sprite(texture.getTexture());
/// window.draw(sprite);
///
/// // End the current frame and display its contents on screen
/// window.display();
/// }
/// \endcode
///
/// Like sf::RenderWindow, sf::RenderTexture is still able to render direct
/// OpenGL stuff. It is even possible to mix together OpenGL calls
/// and regular SFML drawing commands. If you need a depth buffer for
/// 3D rendering, don't forget to request it when calling RenderTexture::create.
///
