the features sound interesting, but where is the code for this? Do you have
a working branch?

I developed those classes while working on SVMT the plugin which displays
sky surveys planning at ESO. They are mostly functional (they are some unit
tests), but are not much used in the base Stellarium. The feature request
from the blue print could indeed be implemented using those classes since
the horizon line (plus the ground below) just form a (very large) polygon.
