annotate test/testloadso.c @ 4593:3892fe2f6537
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.
