    longDescription =
      '' 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)
	    * Custom Blit functions (SDL_gfxBlitFunc.h)

	 The library is backwards compatible to the above mentioned
         code. Its is written in plain C and can be used in C++ code.
