Subject: widget: Don't forget margins when adjusting
X-Git-Tag: archive/raspbian/4.6.5+ds-1+rpi1~1^2~19^2~5^2~125^2~8
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=7459d430eb5a8cd94462b0a1ad068e89384294f9;p=gtk4.git

widget: Don't forget margins when adjusting

This could lead to the wrong values being passed and computing invalid
sizes which would then lead to very unhappy code.

Test included.
