Okay! This method of using FONT=0 and FONT=1 within the cgPlot call works!
See the two plots below, one using FONT=0 and the next using FONT=1.
https://www.dropbox.com/s/sssrxis3gadzmoz/Font%3D0.pdf?dl=0
https://www.dropbox.com/s/snr3g9933o7qda5/Font%3D1.pdf?dl=0
BUT now I want to get this to work after loading a ton of commands into a cgWindow. It seems that theoretically it should work using cgControl, PS_FONT=0, but as Phillip mentioned above, that command is ineffectual. Is this a bug, maybe?
