My VirtualGL lib again - showcase&cry for help

thank you for these tips. some of them made me think. also i couldnt take it this way because i changed a lot since the last version published here.
but i will take a very sharp look at these

here is the new version

(now supporting a z-buffer instead of a w-buffer)


btw:
:)
