DESCR:
The SDL_gfx library evolved out of the SDL_gfxPrimitives code which
provided basic drawing routines such as lines, circles or polygons for
SDL Surfaces.
The current components of the SDL_gfx library are:
- Graphic Primitives (SDL_gfxPrimitves.h)
- Rotozoomer (SDL_rotozoom.h)
- Framerate control (SDL_framerate.h)
- MMX image filters (SDL_imageFilter.h)
