    25  *  Header file for SDL 2D rendering functions.
    26  *
    27  *  This API supports the following features:
    28  *      * single pixel points
    29  *      * single pixel lines
    30  *      * filled rectangles
    31  *      * texture images
    32  *
    33  *  The primitives may be drawn in opaque, blended, or additive modes.
    34  *
    35  *  The texture images may be drawn in opaque, blended, or additive modes.
    36  *  They can have an additional color tint or alpha modulation applied to
    37  *  them, and may also be stretched with linear interpolation.
    38  *
    39  *  This API is designed to accelerate simple 2D operations. You may
    40  *  want more functionality such as rotation and particle effects and
    41  *  in that case you should use SDL's OpenGL/Direct3D support or one
    42  *  of the many good 3D engines.
