Subject: Re: [SDL] Question about SDL_FillRect()
I benchmarked with and without clipping UpdateRects and was unable to find
any difference on my moderately slow machine. Anyway, I haven't added
clipping in this patch, but fixed a couple of bugs and generally cleaned
up some of the X11 image code. Most importantly, UpdateRects now checks
for both zero height and width. Also, I eliminated the entire code to
byteswap X11 images since X11 can do that automatically if you ask it
nicely :-)
