[osg-users] Verify hardware instancing capabilities

[Robert Osfield]

Hi Mateusz,

You need a valid graphics context to be able to test whether an extension
is supported or not.  One easy way to ensure this is to do the test in
aRealizeOperation.  Have a look at the osgvolume example to see how one
tests for graphics capabilities.

Robert.
