Log message (9 lines):
Lambros points out that trying to generate a 3x3 Cairo Easy grid
spins forever, but observes that raising the limit to 4x4 across all
grid sizes is not good for the complex grids like great-hexagonal.
Introduce per-grid minimum sizes using mad macro trickery.

(In fact, for each grid type I've put in a minimum size which _both_
coordinates must equal or exceed, plus another minimum size which
_at least one_ must equal or exceed; that permits both 3x4 and 4x3
Cairo while disallowing 3x3.)
