modules/shapes: add procedural 2D shapes module

Mostly for compositing purposes, here will be a corpus of 2D
shapes, parameterized/procedurally generated and able to rotate
and perhaps have other dynamics added.

What shapes are there presently I had started implementing in
checkers as "styles", before realizing they really should just be
a separate module checkers can call into.

Not terribly interesting by itself, but as blinds and checkers
demonstrated, these things deliver a lot of value in
compositional situations.  They're creating the palette to draw
from.
