The cookbook is meant to be used with pretty much the whole of the 1.0
API; the API is deprecated, but won't ever be removed at this point.

Then it's probably better to stick with it despite the warnings.

You'll likely need the 2.0 experimental Cogl API that Clutter itself uses.

My first question would, on the other hand, be: why are you trying to
define a non-rectangular pick shape?

libchamplain supports various markers displayed on the map. These markers can be clicked, drag-and-dropped etc. so they have to be pickable and can have various shapes (one for instance looks like a rounded rectangle with a tick pointing to the given point on the map).
