/* Abstract base class for objects that can be drawn to a render target.
 *
 * SFML::Drawable defines the attributes and operations that are common to all the drawable classes:
 *
 *   - transformations (position, rotation, scale, local origin)
 *   - global overlay color
 *   - blending mode with background pixels
 *   - the ability to be drawn on either RenderWindow or RenderImage
 *
 * Please note that all these attributes are hardware accelerated, therefore they are extremely cheap to use 
 * (unlike older libraries that perform slow transformations on the CPU, such as rotation or scale).
 *
 * Usage example:
 *
 *   # Here we'll use a SFML::Sprite to demonstrate the features of SFML::Drawable
 *   drawable = SFML::Sprite.new( ...whatever... )
 * 
 *   drawable.SetOrigin(10, 20)               # set its origin to the local point (10, 20)
 *   drawable.SetPosition(100, 100)           # set its position to (100, 100)
 *   drawable.SetRotation(45)                 # set its orientation to 45 degrees
 *   drawable.SetColor(sf::Color::Red)        # set its global color to red
 *   drawable.SetBlendingMode(sf::Blend::Add) # set an additive blend mode
 *
 *   window.draw( drawable ) # finally draw it (window is a SFML::RenderWindow)
 *
 * Deriving your own class from SFML::Drawable is possible, however you have to use the SFML::Renderer class instead of 
 * direct OpenGL calls, which is more limited. To create a derived drawable class, all you have to do is to override the virtual Render function.
 *
 * One of the main benefits of creating your own drawable class is that you can build hierarchies of drawable objects. 
 * Indeed, when you draw a drawable inside the Render function of another drawable, the former inherits the 
 * transformations and color of the latter and combines them with its own attributes. This way, you can apply global 
 * transformations/color to a set of drawables as if it was a single entity.
 *
 * Example:
 *
 *   class MyDrawable
 *     include SFML::Drawable
 *     # ...
 *
 *     def initialize
 *       @myTexture   = SFML::Image.new( ...whatever... )
 *       @mySubSprite = SFML::Sprite.new( ...whatever... )
 *     end
 *   
 *     def render( target, renderer )
 *        # Low-level geometry rendering
 *        renderer.setTexture( @myTexture )
 *        renderer.begin( SFML::Renderer::QuadList )
 *            renderer.addVertex(...)
 *            renderer.addVertex(...)
 *            renderer.addVertex(...)
 *            renderer.addVertex(...)
 *        renderer.end()
 *   
 *        # High-level drawable rendering
 *        target.draw(@mySubSprite);
 *     end
 *   end
