- This originally showed up as fonts rendering differently on X11 than Wayland. (#230) - Setting font size in points should be device and back end independent, however the same exact font face and size, on the same machine, sometimes results in different font metrics between the xcb and wayland Qt back ends. - Setting font size in pixels, assuming a virtual DPI of 96 pixels/inch, results in consistent font metrics and rendering between these back ends. Furthermore, this virtual DPI works for either on-screen or hi-res printer QPainter contexts. - This virtual DPI seems to work correctly with some limited testing with Windows and MacOS. - Add rendering tests to build-tests CI script.
