annotate src/video/x11/SDL_x11render.c @ 4573:6399178be313

Completed work on X11_CreateTexture. Added lots of safety features. These include support for drawing a texture using the core protocol while other textures are drawn using Xrender if Xrender does not support the color format of the said texture or any other fault with Xrender.
