Issue 8: Eliminate most controls in the GUI for iray mode
Project Member Reported by remy...@gmail.com, Aug 12, 2012
Basically 90% of the controls for mental ray have no effect for iray, should be eliminated if possible. Mostly on/off for things like motion blur.

(trace depth should be altered)

Shadow mode removed
Motion blur extra controls
Sample options (Still Gaussian only?)
Error cutoff versus Quality
