And if you add a couple more begin/endEdit()s (for the logo and overlay)
OpenSG will like you, too. ;) If you're worried about performance
(because this does use glDrawPixels()), you put your Image into a
Texture and use the PolygonForeground Andreas mentioned.

At this time, no. You're welcome to add that, just look at
ImageForeground::draw(), it's pretty trivial. I'd recommend using the
Viewport convention (coords <=1 are relative, coords > 1 are absolute).
