MoonlightWave-12 69805b4565 Add more scaling-tests
These are based on actual displays/devices.

A display-size-calculator ( https://www.sven.de/dpi/ ) was used to
calculate the width and height from resolution and diagonal display-size.

Some of these tests check for non-optimal results;
however, their purpose is mostly to make it noticeable
how changes to scaling-behaviour affect various
display-types.

When Squeekboard's scaling-behaviour will be improved, the tests
should be updated with values that fit the displays/devices better.
