More intelligent view rotating - auto re-center focal point for view rotating#24

Model focal point for rotation currently is fit to entire model’s center point. It would be nice to have the focal point self-adjust so that when you are zoomed into a detailed area the model will rotate about the zoomed in area. Rotating while zoomed in rotates can turn the object out of the viewing area.

Also, same could apply to “View down the X/Y/Z axis”. It would be helpful if the zoomed-in area remained the same after rotation takes place.

Rotation gestures assume the center of the scene as pivot point. Such gestures are dragging with the right mouse button, or hitting the arrow keys, or clicking one of the “View down to X, Y, or Z” buttons. To quickly set any point as the center or rotation, right-click on it.
