[osg-users] Please test OpenSceneGraph-3.6 branch in prep for 3.6.1

[Robert Osfield]

Hi Dan,

Could you get teh text.frag working on your machines and then a PR for
OpenSceneGraph-Data for it.  I can then run osg2cpp on it to update
the OSG version.

Thanks,
Robert

I think this was only fixed in drivers in the last year or so.  However, we can always ship out an updated text.frag when/if it gets to that point.
