This sounds plausible, thank you for shedding some light on this! The faking of
large points through triangles in a GS would also explain, why some of my GS
code, I use with large points and for constructing wide lines, doesn't work as
expected. Unfortunately this part of the mesa code seems to have a lot of bugs,
and produces crashes, no rendering output and false rendering output. The same
code works flawless with ubuntu, win7, winxp on nvidia/amd/intel graphics in a
non-vm environment.
