not gs, but a gs driver. That's the main idea behind every modular
system.

no, gs shouldn't need to care about ggi as little as gs should need to
care about X. gs should have a 'driver interface' (much like ggi has
an (internal yet abstract) visual interface) and one such driver would
know about ggi visuals...
Yes, indeed: big prizes for the first to write a ggi driver for gs ! :)
