Add inteligence to "Lock Interactive Render" LOD
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
We need to add some intelligence to the Lock of the LOD. Make this dependent on the time for a still render - if it is over 2 seconds, then keep the LOD rendering for the amount of time on the Lock Interactive Render time. Otherwise, turn it off. This will allow users to place very large, slow objects, while not penalizing users that are rendering quickly.
