ZFP - Improve default mouse cursor shape on viewports

Doctors use ZFP when he/she explain the status to their patient(and patients relative).

In such case, doctors wants to point the region of interest in the image by mouse cursor.

By default, the mouse cursor of ZFP viewer is scroll mode's one, it is hard to identify where is pointed it.

As a workaround, we offered to click the measurement tool icon to change the mouse cursor to an allow shape, but the customer didn't accept it because he/she doesn't like to click once more.

In addition, UV viewer's mouse cursor of scroll mode is an allow shape.

So I require that ZFP's mouse cursor of scroll mode is changed to an allow shape same as UV viewer.
