VIEWMODE
Retains the view mode for the current viewport. The value is a bitcode and can be any combination of the following:
0 = Turned off
1 = Perspective view turned on
2 = Front clipping turned on
4 = Back clipping turned on
8 = UCS follow mode turned on
16 = Front clip turned on but not at camera point. If on and bitcode 2 is on, the front clipping is determined by FRONTZ. If off, the front clipping is determined through the camera point.
