- Renamed lots of UI text and tooltips to improve UX - Hid the 'Propagate' and 'Per Instance' buttons until this feature is properly supported - Flipped radio buttons so they're on top of 'instant' buttons - Renamed 'Any' to 'Mesh' in the top level UI (meaning, 'any part of the mesh') - Added group name title text for 'Mesh', 'Polygon', 'Edge', 'Vertex' - Reversed order of top level buttons, removed 'Select' label - 'Remove Subdivision Level' now greys out if there is nothing already subdivided - Fixed lots of non-unity build issues #codereview richard.talbotwatkin #rb none [CL 3509887 by Mike Fricker in Dev-Geometry branch]
