In order for ristretto to show webp images it requires the package gui-libs/gdk-pixbuf-loader-webp to be installed.
Hence, is it possible to add webp as a use-flag for media-gfx/ristretto which will install this package?
I suppose this is true of all packages using gdk-pixbuf.
@gnome, is there some global idea for handling this? I suppose all software using gdk-pixbuf declaring pure conditional RDEPEND on gdk-pixbuf-loader-webp is going to suck, especially if webp support ends up being integrated into core gdk-pixbuf at some point.
