title: SDL_SetVideoMode Desired vs. Obtained
body: <p>I'm writing programs in C that use SDL for graphics. I have my program optimized for writing video in a 32 bits per pixel mode. I just go along each scan line writing blue, green, red, skip, blue, green, red, skip, blue, green, red, skip (skipping those extra bytes in the 32 bpp format). Is there any chance this could fail? Could SDL deny me 32 bpp and give me something else instead? Could the byte offsets of different colors end up in a different order and screw up my program?</p>
