*
|
|
* SFML::Renderer is the abstraction layer between SFML code and the low-level drawing API (OpenGL).
|
|
*
|
|
* It manages render states efficiently, and provides a lightweight abstraction for rendering geometry.
|
|
*
|
|
* The purpose of this class is to provide a single abstract entry point for everything related to low-level
|
|
* rendering. Hiding everything behind SFML::Renderer makes optimizing easy, as well as porting to other technologies
|
|
* in the future (like OpenGL ES or OpenGL 3.x).
|
|
*
|
|
* This class is mainly meant for internal usage, you should never care about it unless you write your own
|
|
* SFML::Drawable class that uses raw geometry in its Render function.
