macOS: screenshot Image Resolution initialized to 2X locked view size on Retina display
Observed Behavior
On macOS with a Retina display, ParaView's Save Screenshot Options dialog initializes the Image Resolution to twice the Render View resolution. My guess is that the 2X resolution scaling factor on Retina displays is coming into play here.
Expected Behavior
Initialize the Image Resolution option in the Save Screenshot Options to the same resolution as the Render View.
