Add Fontmatrix to abstractions/fonts
Fontmatrix adds ~/.Fontmatrix/Activated to fonts.conf. This causes programs which use Fontconfig (directly or indirectly through libraries such as Pango) to include that directory in their font search path, which causes errors such as:
audit: type=1400 audit(1602678958.525:53): apparmor="DENIED" operation="open" profile="fr.emersion.Mako" name="/home/username/.Fontmatrix/Activated/.uuid" pid=48553 comm="mako" requested_mask="r" denied_mask="r" fsuid=1000 ouid=1000
audit: type=1400 audit(1602678958.525:54): apparmor="DENIED" operation="open" profile="fr.emersion.Mako" name="/home/username/.Fontmatrix/Activated/" pid=48553 comm="mako" requested_mask="r" denied_mask="r" fsuid=1000 ouid=1000
if the program does not explicitly include this directory in its
AppArmor profile. As with other common font locations, add
~/.Fontmatrix/Activated
to the fonts abstraction for read-only access.
Thanks for considering, Kevin
