Crop Widget

[aylward]

In the quad view, in each 2D view, we should be able to turn on "cropping". This allows the edges in the 2D image to be moved in to specify a cropping plane in the 3D view.

Forrest has created the 2D crop interactor/widget already.

Cropping icon should appear in the bar associated with each 2D view (e.g., in-line with the orientation and reset icons). The cropping icon should be the standard crop symbol - see attached.

A few things needed in the crop widget before integration:

• volume cropping: volume is currently not yet cropped via cropping planes
• handling orientation: do we force all slice views to ignore orientation, or change the cropping widget to support orientation?
