Search the Mesa source for all of the occurances of 'if
(ctx->Visual.rgbMode)' and you'll see most of the reason I want to
remove it.  Commenting it out or ifdef'ing it out will actually make the
situation much, much worse.

Part of the reason I want to do this is that I'm working on an extension
that allows the creation of a context without a visual / fbconfig.  I
have this mostly working, and I should have patches out early this week.
 The biggest hurdle has been "fixing" all of the places that use
ctx->Visual.  90% or more of those places are checking rgbMode.

Ideally, I'd like ctx->Visual to be completely removed.  99.9% of all
places that use ctx->Visual should actually use ctx->DrawBuffer->Visual.
 I suspect that this accounts for some of the FBO rendering problems
that have been reported over the years.
