Some time ago we got bug report for OSX, who say about OpenGL 2.1 within
Stellarium and OpenGL 3.2 in other application (I don't remember name of
application - he was showed diagnostics info). It can be related to Qt.
Plus today I got a strange issue in diagnostics info on Windows within
VirtualBox (when I built 0.13.1.87) - he (VBox) has support OpenGL 2.1, but
Stellarium determine it as OpenGL version 2.0 and, of course, he won't run
now.
It's (support OpenGL on different platforms) really annoying :(
