I'm curious though, is this a bug in Wine, or is it a bug in The Swapper that
just happens to clash with Wine? Because I see hundreds (a rough estimate) of
functions in opengl_norm.c that makes the same assumptions that glBindTexture
and glDeleteTextures do. Should the error checking be added to all of them too?
