Exactly this should be set by an easy to use interface. Similar to the already
existing DPI switch in the advanced font dialog, but this is too hidden, and an
user will not know what a "DPI" is, or how to calculate it properly. That's why
I proposed to show two rulers the user can measure.

It already is, it just should be done more obvious and easy.
