/* GLView: A basic OpenGL rectangle for rendering images.

Inherited by QGLview (for QT GUI) and OffscreenView.

There are two different types of cameras. A 'gimbal' based camera set
using position & euler-angles (object_trans/object_rot/distance) and a
'plain' camera set using eye-position, 'look at' center point, and 'up'
