commit bf8a43a9037d65f38db6115d4d8133499f86cebe
Author: Michael Meeks <michael.me...@collabora.com>
Date: Thu Aug 20 17:03:30 2015 +0100
tdf#93547 - Disable OpenGL if we have a SEGV on windows in that code.
Annotate when we are in an OpenGL rendering zone.
Check for this in the VCL signal handler, and force OpenGL off here
if exception occurred inside an OpenGL code-path.
