(svn r11342) -Fix: [OSX] The cocoa driver incorrectly assumed that the blitter always was 8bpp. Now both 8bpp and 32bpp blitters can be used. The driver will check the blitter screen depth. In fullscreen it will select a proper video mode for this depth, and in windowed mode it will simply skip doing fake 8bpp.
