VRaySceneTranslator - add option to use active viewers ROI for crop and region renders

[frueter]

another one:
for both the "region" and "crop" parameters in the render output group it would be nice to have a button that simply copies the values from the active viewer's ROI, i.e.

nuke.activeViewer().node().roi()

Cheers,

That sounds like a pretty cool idea - I will add it to the to do list.

Thank you,
