(svn r10121) -Codechange: split renderer from rest of code; no longer any code directly accesses the video-buffer
-Add: added NULL blitter and renderer, which are always used for -vnull -Add: dedicated driver doesn't blit nor render by default. Can be overruled by user. (-D -b 8bpp-optimized) -Remove: removed CTRL+D from win32, which is incompatible with above -Add: extended screenshot support for PNG and BMP -Codechange: remove all hardcoded 8bpp references and replace them with more dynamic ones -Codechange: minor stuff in blitters
