annotate src/video/x11/SDL_x11video.c @ 270:37fa1484f71b

From: "Mattias Engdeg�rd" <f91-men@nada.kth.se> To: slouken@devolution.com 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 :-)
