First, add automatic detection of toolkit DPI scaling options. For now, this is, in order, * Check the GDK_SCALE option under GTK+ (users can set this to force the scaling) * Check the value from WX's GetContentScalingFactor(). This will start to work correctly from WX 3.1 and GTK+ 3.10. Then, add a user-settable override in the main prefs panel, next to the icon scaling. This is independent of the icon scaling options. DPI handling is performed in a standalone class, so they can be shared between the prefs UI and the OpenGL backend easily. Also means Cairo could use the same interface in future. Also adjust the OpenGL grid drawing code to use the computed scale factor, which avoids over-thick grids in scaled environments (the user can manually thicken the grid if wanted).
