#68 zoom in/out around mouse pointer

[Dominique B.]

In 3ds max you can zoom in to the spot where the mouse
pointer is currently - so not using the view middle.
Same for zoom-out. It's an option, so the user can
decide if he wants to zoom in/out via the viewport
middle or the mouse pointer.

Needs a bit of time to get used to it but then very
very useful.
