If reasonably possible, we'd like to avoid matching on gl_vendor and
the like. It's not the most reliable information we have, and would
prevent the feature from working in the future if the driver is ever
fixed. I'll grant the chances aren't great on the latter, but out of
principle, it should be possible to test if the feature itself is
working.
