Description
When using ofEasyCam extensively for a project I noticed that the rotation behavior starts to get funky as you translate the camera away from its origin.
ie: If you have a really long line extending out from (0,0,0) and then you translate to the end of the line ( using the alt key modifier ) when you rotate (using left click mouse drag) the rotation is still happening around the origin, vs around the center of the camera view ( which is closer to what I was expecting ).
It seems:
https://github.com/elliotwoods/ofxGrabCam
has the expected behavior - is this something we would want to bring into ofEasyCam?

Research direction
Start by comparing ofEasyCam's translated-camera rotation behavior with the expected behavior described for elliotwoods/ofxGrabCam. Determine whether the upgrade should make left-click rotation follow the camera view center rather than the origin, and confirm that behavior with a long line translated away from (0,0,0).
