Several things in the GNOME stack have file-based caches, like gdk-pixbuf's loaders.cache. These need to be regenerated, and historically that worked in jhbuild because these modules include bits in their Makefile to run then relevant commands, if DESTDIR is not set. Package managers have post-installation scripts in packages, and OS builders typically support this as well. Jhbuild historically relied on the post-installation scripts in modules, but in (see bug 647231) we switched to using DESTDIR for all module types. So we need to move closer to the package model here. We call them "triggers" as they're run after any kind of build operation (including "uninstall"). This patch adds a proof-of-concept trigger script for gdk-pixbuf loaders. https://bugzilla.gnome.org/show_bug.cgi?id=653842
