GDK Quartz Pen tablet support (pressure, tilt, wheel)
Migrating from bugzilla: https://bugzilla.gnome.org/show_bug.cgi?id=695701
There was some progress, including a patch, but it stalled because it wasn't using the new tablet api, and other reasons. I would really like Quartz Pen support so we can use MyPaint on MacOS. I believe X11 does work but homebrew has already removed X11 support so that's not a great option.
Pressure in GIMP does appear to work on MacOS and in Quartz, but I don't know why (a GIMP-specific work-around?). gtk3-demo does not detect any pressure or tilt from my Wacom tablet. Tested with gtk+ 3.22.30 via homebrew on MacOS Mojave
