They are. Their icons at least, see
https://git.gnome.org/browse/gimp/tree/themes/Default/images/Makefile.am#n394

Then those projects might be a) unaware of this, b) might not compile in
their icons or c) might have solved the problem. If there is one,
https://www.gnu.org/licenses/license-list.html#OtherLicenses lists
CC-BY-SA version 2.0 as being incompatible and does not mention later
versions.

Yes, but those are not part of the compiled code. And we want to do this
explicitely to avoid confusion about whether images created with such
brushes and patterns would have to be licensed under the GNU GPL.
