Fixed so many things. See the changelog listed below. 1. Use SDL_X11_HAVE_XRENDER to check for RENDER at runtime. 2. Added lots of comments. 3. Added checks and lots of calls to SDL_SetError(). 4. Fixed X11_CreateTexture() so that the pixmap and image created are for the format specified by the user and not the window format. This is only for the RENDER case. 5. The above change required that functions to convert SDL pixel format enums to Visuals and XRenderPictFormats be added. 6. Fixed lots of 'style' issues.

9907c8cc6015 X11_RenderFillRects and X11_RenderDrawRects use a server side mask pixmap of 1 bit depth now. All drawing on these pixmaps is done by server side functions such as XDrawRectangles and XFillRectangles.
