This should not be proposed into xenial as it breaks automatic rescaling when moving between displays of different pixel densities. If you would like to propose this, first find a way to diagnose that Qt auto-scaling is not working, then use this workaround based on that knowledge. Make scaling work correctly on different size displays that don't have auto-scaling by dividing the current GRID_UNIT_PX by the default (8). Works around ubports/ubuntu-touch#1320

Let's repeat #841 again, but this time for Wayland! Yaaaaay!
The Qt autoscaling doesn't work under QtWayland on Ubuntu Touch, instead returning
1for any sized screen. Instead, thepixelDensity()function of the QtScreen should return a number based on how large the screen is. This causes Kirigami and similar apps to not scale at all.This was fixed in QtUbuntu with ubports/qtubuntu#5. It's possible that QtMir is not passing a required value to QtWayland.
