[Mesa3d-dev] more lighting fixes

[Brian P. <br...@pr...>]

I've been spending the past few nights fixing GL conformance
failures in Mesa 3.2 and 3.3.  I finally fixed the last lighting
bugs.  The most recent changes fix the (somewhat broken) handling
of ambient lighting terms.

If anyone has suspected that their ambient lighting wasn't coming
out correct please grab the latest Mesa 3.2 or 3.3 code out of CVS
and test.

As of now, Mesa 3.2.x now only fails AA points and AA triangles but
those have been fixed for 3.3.

Mesa 3.3 now passes all GL conformance tests except line stippling.
That shouldn't be too hard to fix.

I've got a couple other tiny bugs to fix in 3.2 before I make a
3.2.1 release.  A 3.3 release should follow soon after.
