We could also follow Clutter's way.  As I am trying to make libchamplain
not depend on Gtk+,

I think that the Gdk/PixBug API is available as a standalone library as it doesn't require Gtk2. On my Ubuntu system I can find
libgdk-pixbuf-dev which provides gdk-pixbuf/gdk-pixbuf.h
 
Isn't libchamplain already using the Gdk/PixBuf API for rendering the tiles? If yes, the how is avoiding the depedency to Gtk2?

we could still put a Gdk/gtk dependant method in the
libchamplain-gtk module: clutter_marker_set_image_from_pixbuf.  Would
that be useful?

This will be useful but a bit restrictive as it would only work for markers. What if we would like to download a logo for a new map provider or put some random image in a fixed button? I think that it would be nice to have a generic method that transforms a GdkPixBuf into a CairoTexture.
