create a `new' stack-allocated instance of an object; just From,
possibly different versions with different arg types.

csg ops; so the union of a red part and a blue part has both red
and blue faces. And some user interface to pick the color in the
text window.
The metadata also include a face, which will be an entity; I can
use that to constrain against. But none of that is yet implemented.

set of coplanar faces. The polygon count still gets stupid fast;
I'm thinking I can fix that by adding some extra test planes at the
top of the 3d BSP, to quickly cull out stuff that doesn't intersect
us.

a triangle mesh in a BSP. That works, although it splits too often,
the initial triangulations are not good quality, and coplanar faces
are not yet handled. I'll do the coplanar thing tomorrow.

for that, and storing the triangles instead of rendering them
immediately. Not sure if that's smart; in theory could change from
implementation to implementation, but the results look much better
than I would get myself.

not very well; I'm doing a b-rep, where the boundaries are complex
polygons, and there's too many special cases. I should probably
replace this with a triangle mesh solution.

sketch (e.g., a line whose length is constrained gets deleted, but
the constraint is left behind; or the point that's the origin for a
drawing group in plane gets deleted), then deleted the dependencies
too.

workplanes. And fix up our polygon normals, so that everything gets
shaded correctly (and so that later we can generate our STL files
with correct normals).

faces of the polyhedron. And shade the faces when I draw them, and
fix up our projection matrix so that the depth testing works
properly.
