Please review the previous conversation between Alexandre and I.  You may
find most of it at:

https://bugzilla.gnome.org/show_bug.cgi?id=625213#c5

Search for pixbuf throughout the bug entry.

We decided on the compromise that gdk-pixbuf would be an optional
dependency for libdmapsharing. Everything needs to work without
gdk-pixbuf, with the exception of things like scaling and converting
images (everything can work without gdk-pixbuf, as long as additional
constraints are placed on how the images are stored, i.e., small and in
PNG). This is similar to how libdmapsharing uses GStreamer. Everything
works without it, except transcoding. As long as media is stored in a
format supported by the clients, nothing is lost. I would like things
to continue in this manner for the reasons noted previously.
