Hi Thomas,

I'm gonna try to find some time during next week to put together a
patch and propose an initial API.
Working from there would be a lot easier for me. If adding custom
colours is gonna be a hassle theming wise I might consider dropping
support for that and just offer generic search match support similar
to what GtkScale does but without any string.
