OK. BTW on the system I’ve set up I position and resize windows with the
WM (FVWM), and there are no issues with `GDK_SCALE`. If I specify that a
window should be sized 2000 × 1000 px, then it’s set to that size.
`GDK_SCALE` only affects the contents of the window.

0.5 is not an integer. ;-)

Why bother? Don’t fonts get rendered via the GTK+ API?
