  *  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.
