Today I've pulled and recompiled Mesa from git and noticed a regression since
the 2010-06-14. The hypertorus hack from XScreenSaver has triangles visible on
strips, that were not visible before. This is on HP Compaq nx6325 laptop with
integrated graphics with RS482. The same problem does not happen on my desktop
computer with Radeon 9600 Pro (RV350 AR).

The last commit that works fine is:
5d4d4b2134595c4ed8060d6d002a0cd54690c289
i965: Remove unnecessary header.

Than there are two commits that don't compile:
b85a361ccbac956d2842251395c048a4b3f4c440
draw wip
92e521a79982f19279f72c34772d33c9c28e2bed
softpipe/gs: fix a crash when a gs isn't present

And the first commit that compiles and doesn't work fine is:
a192b5eeafae80f9f9e7e7e442abc5b44d583d1a
draw: finish the new pipeline setup

This is a bug in Draw (the module we use for SW TCL). I guess this will be
fixed once Zack Rusin finishes his work on Draw, hopefully.
