Automatically rotates GL camera.

W's are angular velocities.

ATheta – Theta amplitude in units of Pi/2.
ADolly – In/out amplitude in units of initial distance.

Can also save images automatically.

fGUIOutMode is used internally between TGLAutoRotator and TGLViewerEditor, allowed values are:

animated gif
a series of png images
