[Mesa-dev] [PATCH 20/22] nv50, nvc0: Support BGRX1010102 format for visuals.

[Ilia Mirkin]

Why is this required? Can't you just use the BGR10_A2 format directly?

The problem with exposing these sorts of formats is that blending with
DST_ALPHA would be incorrect -- it should get read in as 1.0, but will
end up with bogus values.

Cheers,
