Subject: widget: Mark compute functions as G_GNUC_WARN_UNUSED_RESULT
X-Git-Tag: archive/raspbian/4.4.1+ds1-2+rpi1^2~18^2~21^2~664
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=02e856f62e9eee7796bdff9ba8d8a9bda31c60fc;p=gtk4.git

widget: Mark compute functions as G_GNUC_WARN_UNUSED_RESULT

Lots of code does not error-check these functions, and when we add CSS
transforms, they will start failing. And we want people to check that.
