More overflow:hidden and rounded frames
This merge request has following changes:
- Set
GTK_OVERFLOW_HIDDEN
in some container widgets to not draw children outside of them. -
Make frames rounded in Adwaita as per GNOME mockups.Partially moved to !2476 (merged). -
Minimal fixes to avoid double borders in some demos and inspector. (They are also intended to make the rounded frames look not-so-bad... but in any case double borders are ugly.)Moved to !2478 (merged) & !2477 (merged).
Example of the rounded frames:
