Summary0012115: FixedPointRayCaster gives different results depending on number of threads
DescriptionThe dashboard test TestFixedPointRayCasterLinearCropped.tcl fails when run on machines with a large number of CPUs. The problem can be simulated on any machine by pumping up the number of threads.

vtkMultiThreader multithread
multithread SetGlobalDefaultNumberOfThreads 64

Then run the test via ctest. It will produce an incorrect image.
