I'm getting a bit concerned about how bloated the format table is
getting. The old table had 184 entries each of which was 32 bits.
Now we're looking at more like 32 bytes per entry and most of it isn't
used for your average format. It probably isn't a huge deal but it
does seem a bit excessive. I'm not quite sure what to do about it though.
Maybe some kind of linked list in the style of pNext in vulkan?
