I ask, because in the interest of moving along, I wouldn't want GLSL on the mac to be the only thing holding up a release.  However, a regression is not desirable at all, and I would hope that running with -no_glsl would get at least the same quality as it did in 3.6.9.  Since it doesn't, that's a separate bug of its own, but it's likely related to the problems with GLSL.  Either way, I would hope to at least get it back to the state it was in, so we could get 3.6.10 out the door and attempt to fix GLSL on Macs at a later date.  I'd prefer no steps forward or back than anything else at this point.
