vtkPlaneWidget Sphere Resizing
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
If make a call to SetHandleSize() for this widget, the Handles are originally sized correctly. However, Each of the On*ButtonUp methods make a call to SizeHandles(). This resets the handle size, eventhough I have previously called to SetHandleSize(). I have commented out the call to SizeHandles() and this can be eliminated while retaining the expected behaviour.
