@Jim again I should have continued reading the link I sent before sending that message. It turns out that to set DPI awareness either SetProcessDpiAwareness() must be called "prior to any Win32API call that forces the system to begin virtualization" preferably instead DPI awareness should be set in the application manifest. Within plplot we are therefore in no position to be able to correctly set dpi awareness. I think this gives an even stronger case for simply using a fixed default.
