* Add radial display mode to preferences
* Adds isRadial to grid
* Improve mesh lines for radial cells
For temporary radial LGRs, show mesh outline based on the aggregated geometry of all LGRs of the parent cell clicked on.
* Improve warning message
* Modify cell selection in pick event handler
* Show timing for geoBuilder.generateSurface()
* Check state of element vector result before geometry is created
* Improve performance for isFaceVisible
Avoid calling costly function cell() when possible
Remove check on fault geometry as this does not affect the visualization
* Performance: Avoid traversal of all cells when computing visibility
When we have an active cell grid, we can skip checking for inactive and invalid state.
Use the list of active grid cells when looping through cells.
