Detailed Description

This group of operators come in several forms:

1. Scroll-wheel 'steps' - rolling mouse-wheel by one step zooms view by predefined amount.
2. Scroll-wheel 'steps' + alt + ctrl/shift - zooms view on one axis only (ctrl=x, shift=y). XXX this could be implemented...
3. Pad +/- Keys - pressing each key moves the zooms the view by a predefined amount.

In order to make sure this works, each operator must define the following RNA-Operator Props:

• zoomfacx, zoomfacy - These two zoom factors allow for non-uniform scaling. It is safe to scale by 0, as these factors are used to determine. amount to enlarge 'cur' by. Temporary custom-data for operator.
