JEDI-SDL is rather large. It contains import libraries for many SDL 
sattelite libraries, many examples and documentation. It is under somewhat 
active development by Dominique Louis.

We could limit ourselves to sdl.pas. This is the main library. All 
graphics formats stuff, 3D stuff etc. is of less importance to graph.

SDL is LGPL, so is JEDI-SDL. We would need ask Dominique for permission of 
the FPC static linking exception to just JEDI-SDL (we do not distribute 
SDL itself). I don't think this will be a problem.
