The DisplayInteractor should support configuration of mouse axis and mouse movement direction for specific interactions:

Zoom:

• updown vs leftright
• invert axis yes or no

Scroll:

• updown vs leftright
• invert axis yes or no

Move:

• invert axis yes or no

levelwindow:

• updown vs leftright (for level, window is set implicitely)
• invert axis yes or no

Some of these options are already available, the others are still missing (e.g. all invert axis options).
