Summary: FixedPointRayCaster gives different results
depending on number of threads
Description:
The 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.
Steps to Reproduce:
Add the following lines to the beginning of
TestFixedPointRayCasterLinearCropped.tcl
vtkMultiThreader multithread
multithread SetGlobalDefaultNumberOfThreads 64
Then run the test via ctest. It will produce an incorrect image.
