games SDL graphics drawing primitives and other support functions The SDL_gfx library evolved out of the SDL_gfxPrimitives code which provided basic drawing routines such as lines, circles or polygons and SDL_rotozoom which implemented a interpolating rotozoomer 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) The library is backwards compatible to the above mentioned code. Its is written in plain C and can be used in C++ code.
