"""Measure what actually breaks on a small screen, screen by screen.

A pane is "clipped" when the width it is given is smaller than the width it says
it needs (minimumSizeHint): Qt then cuts content off instead of shrinking it,
which is what shows up as half-drawn buttons and cut-off labels.

Reports per destination, at a few window sizes, and lists the widest offenders
so a fix can be aimed at the right widget instead of guessed at.

Run:  python tools/check_responsive.py [width height ...]
