* \file SDL_render.h
*
* Header file for SDL 2D rendering functions.
*
* This API supports the following features:
* * single pixel points
* * single pixel lines
* * filled rectangles
* * texture images
*
* The primitives may be drawn in opaque, blended, or additive modes.
*
* The texture images may be drawn in opaque, blended, or additive modes.
* They can have an additional color tint or alpha modulation applied to
* them, and may also be stretched with linear interpolation.
*
* This API is designed to accelerate simple 2D operations. You may
* want more functionality such as rotation and particle effects and
* in that case you should use SDL's OpenGL/Direct3D support or one
* of the many good 3D engines.
