VOXEDIT: Live destructive transform (rotation/translation/scale/etc) gizmo

[Metadorius]

This feature is available in MagicaVoxel. From my understanding it doesn't apply the changes until you deselect the tool or select something else, so doing any amount of clicks before "committing" the changes won't lead to quality degradation from re-voxelizing.

Could also add shear and other transformations like in 2D editors, or transform using handles:

Probably a special handling needs to be done in order to rotate/scale the normals too, since after transformation they would be incorrect if not handled.

Additional consideration: in some cases one has to use specific angles or values to rotate, like if one, for example, wants to do rotors or something like that. In that case an ability to specify precise angles has to be added. In MagicaVoxel, that is a separate tool, but I think augmenting this gizmo with such features is going to be better.
