More in-depth tracing for when we pick an fbconfig for a visual that
we haven't seen attribs for (via glXChooseVisual).
I used this when an NVIDIA driver with specific Quadro card (and only
32-bit, not 64-bit!) was giving a weird StaticGrey 128bit visual when
_MatchConfig asked for something more regular. Turns out the spec says
the visual was legal, just not what you normally get. I think this
trace info is generally useful.
