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.
