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.
