Fix Sculpt Gestures using normal orientation with translated objects

This fixes two issues that were preveting normal orientation for working:

- The translation of component of the object matrix should not be
considered when converting a normal to world space.
- Whe using cursor for depth, the depth for the shape should be taken
directly from the cursor (which is already unprojected and updated)
instead of from the brush, which may have not been updated.
