Detailed Description

Scrollers should behave in the following ways, when clicked on with LMB (and dragged):

1. 'Handles' on end of 'bubble' - when the axis that the scroller represents is zoomable, enlarge 'cur' rect on the relevant side.
2. 'Bubble'/'bar' - just drag, and bar should move with mouse (view pans opposite).

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

• deltax, deltay - define how much to move view by (relative to zoom-correction factor)
