[vbox-dev] OpenGL/3D on Mac Hosts... Screenshots

[Louis King Jr]

Yes, it's always been a 3D problem. 3D has always been problematic with the
Mac version of VirtualBox. The screenshot problem for 3D has been going on
for something like 3 years. 2D screenshots are fine.

I figured the errors weren't too meaningful but I thought I should include
them.
