Ship icon assets used by GTK
GTK (both 3 and 4) uses various icon names internally, expecting them to come from the icon theme. There is a unit test that asserts that all these icon names still exist, testsuite/gtk/check-icon-names.c
. The recent removal of lots of icons from adwaita-icon-theme makes this test fail.
For example, GtkVolumeButton
uses audio-volume-high-symbolic
by default, but audio-volume-high
if the GtkVolumeButton:use-symbolic
property is set to false.
Please coordinate with the GTK maintainers to make sure that at least one of GTK and/or adwaita-icon-theme is responsible for shipping all the icons that are required by the latest GTK release on each maintained branch.
