Please read what you are replying to; as has been mentioned *several*
times, one of the needs is to specify the location in GL world space,
not screen space.

In the long run, I hope that Qt3D will bring this functionality back,
only "the right way" (i.e. using a billboarded sprite rendered in GL...
the texture can of course be created using QPainter).
