I did some more testing and it is not a problem with my local setup, as
I can get correct GPU-based volume rendering with PV 3.12.0 in the
following two situations:

* Running PV standalone on a render node under VirtualGL, accessed
through VNC
* Running 1 pvserver on a render node with forced remote rendering
(remote rendering threshold enabled and set to 0)

However, when I try to use 2 or 4 pvservers (one per render node) I get
the purple-square-screwed-up rendering, both with 3.10.1 and 3.12.0.

Surprisingly, with 3.8.1 when using 2 or 4 pvservers the GPU-based
rendering works...
