And now that the FrameBuffer class is partially working, time to break
things again :) Work continues on refactoring the FBSurface code, and moving thing out of the xxxSDL classes that don't really have anything to do with SDL. This will also make it easier to port Stella to other graphical toolkits. git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2878 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
