Off by one pixel multiview windows
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
When you are in client server mode and are doing image compositing, there is sometimes an off-by-one error that occurs when reading back images when you have multiple windows. Sometimes on the left and/or bottom there is a pixel-width worth of image read back that is garbage.
The arithmetic in vtkPVDesktopDeliveryServer is probably wrong. My guess is that it is computing the offset of the viewports to be a little too far to the upper left.
