Fixed bug #761
Mason Wheeler 2009-07-05 09:28:33 PDT
This patch fixes two issues with SDL_CreateTextureFromSurface.
1. If no renderer is available, the function will return 0 without calling
SDL_SetError. (It does this in other places as well, but it appears that in
these cases, SDL_SetError was already called by a previous function call.)
2. Removal of a dead code block that checks for an impossible return value.
