I'm trying to implement something regarding DPI/Font to Qtf and I need to determine screen DPI. Something like Draw::GetPixelsPerInch seems a good place to start, but first of all I can only call it on a Draw instance, and even if I do, I get a failed assert regarding IsDrawing. Using it on ScreenInfo also seemed like a good idea, but I can't use it or find it's definition. All I can find is about 6 such declarations scattered around:

Draw& ScreenInfo();

Also, could someone point me in the direction where GUI scaling is done, so I can understand the way sizes scale with higher DPI. Is it CurDPI / 72 * intended size or something similar?
