The following improvements have been implemented to the measuring tool in 3d scenes:

• Allows measuring on point cloud points
• Display billboard circle markers on the 3d rubber band's vertices
• Moving the mouse moves the rubber band's last vertex (although the measured results are not updated until user clicks)
• Moving the camera does not remove current measurements
• Allows using backspace and del keys to undo (remove last measurement)
• Allows using Esc to clear measurements, matching the behavior of its 2d counterpart
• Renders 3d rubberbands on top of other 3d entities so they don't get occluded

The object selection logic has also been refactored for more control, and the 3d identify tool was also enhanced to prevent interference with camera navigation as well as a bug fix for where the wrong FIDs were returned on specific cases.
