Bug#1075937: breeze-gtk-theme: Change `gtk2-engines-pixbuf` dependency to recommends so GTK2 isn't mandatory

[Sam Uienn <samuie@fastmail.to>]

Package: breeze-gtk-theme
Version: 5.27.11-1
Severity: wishlist

Dear Maintainer,

Could `breeze-gtk-theme` list `gtk2-engines-pixbuf` as a recommends instead of a depends?

It's the only package on my system that depends on the GTK 2 libs, and I wouldn't be surprised if 
this is the case for others too, so it would be nice to get rid of this hard dependency.

Thanks for considering,
Sam
