Need to multi-sample when depth peeling is off.
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
When Edit/ Settings/ General/ Enable Depth Peeling is unselected, please make ParaView multi-sample. This is to work around issues with some graphics cards that stop antialiasing. (I believe that the call that needs to be called is SetMultiSamples() with some unknown input other than 0).
