Getting more information from mouse pointer in 3D view

I think this might solve part of my problem:

Segment Editor and rotate/tumble/orbit function in 3D view

I’ve made painting/erasing in 3D view optional. It should be available in nightly builds that you download tomorrow or later. I’ve also added “smudge” option to Paint effect: auto-select segment at click position, which should help in minimizing switching between segments when adjusting boundaries between them. I’ve also added option to erase all segments (not just the selected segment) using Erase effect.

This seems to hit the model in the 3D view and identify the slice coordinates? if so i need to capture the mouse click-events en calculate the RAS coords.
