[Feature] Camera Pan and smooth move in and out

[gameengineer]

Adding pan movement to the orbit camera would be nice addition. Panning would move the "look at" target and therefore rotations would still orbit around the new location. Smooth in and out movement using mouse click+drag in addition to wheel wheel steps would also be a nice addition. Perhaps right mouse which really isn't used for anything new here could be used to smoothly move in and out. Hold RMB+move mouse up moves in and down zooms out or something like that. You could also use the middle mouse button instead of the right mouse button for movement.

The in/out movement is separate from zooming which affects the FOV. I am not suggesting a zoom feature here.
