"Alloc for render" is a terrible name for a flag because it means basically nothing. What the flag really does is allocate a busy BO which someone theorized at one point in time would be more efficient if you're planning to immediately render to it. If the flag really means "alloc a busy BO" we should just call it that. Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>
