Apart from the fact that this comment still doesn't make sense (it
should probably have an additional 'on'), I'm not sure why we have
this fallback in the first place.  If the dc or bitmap creation fails
then we've probably got bigger problems.  I'd suggest just returning
early in those cases (with the appropriate cleanup).
