and fix some other issues, to make the layouts more consistent.
The aspect-ratios of the layouts,
should now match the intended aspect-ratios (12:7 and 16:5),
with 3 decimal-digits of precision; either exactly,
or rounded to be a little more square,
so that the entire height of the panel will be used.
Adding 0.001 to `width` in the `default`-outlines of the layouts,
would make the layouts a little wider than the intended aspect-ratio.

Currently this differs for the same view-change-keys in different layouts.
When the text is "abc", the size of the key's text changes
when toggling between "123" and "abc"; with the text "ABC",
the size remains about the same.
