Remarks
color should be a pixel of the format used by the surface, and can be generated by SDL_MapRGB() or SDL_MapRGBA(). If the color value contains an alpha component then the destination is simply filled with that alpha information, no blending takes place.
If there is a clip rectangle set on the destination (set via SDL_SetClipRect()), then this function will fill based on the intersection of the clip rectangle and rects.
