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.

not have much motivation behind them, but they seem to work. And
make sure that we don't solve multiple times without repainting in
between, and tweak the text window a bit more.

foreground and background colours are now specified separately, and
it's possible to insert half-line spaces. So now I have a window
that lets me show/hide groups, and select the active one.

other entities. This requires a new point type, for a point that's
defined as a transformation of some other point. All works nicely,
I think. There's ugliness because entities are no longer guaranteed
to have a parent request.
Also speed up display of the text window, by caching brushes
instead of recreating for each character (!), and add a bit more
user interface in the text window.

locked on to the XY plane. And simplify the handling of colors in
the text window: identify them by a character, not an integer ID,
since the character is easier to remember.

stuff, though no file load stuff, and perhaps this can all be made
to work from a table somehow. Move the quaternion stuff into its
own class, and add a fancy animated view when you orient onto a
csys.

expressions that we wish to keep around. And make the 2d coordinate
system (that causes points to generate 2 unknowns, not 3) an
attribute of the request, not the group, and add user interface to
change that.

syntax tree. That's what I'll used for entered dimensions, and
algebraic constraints and such. Needs to be extended to handle
stuff like points and entities, but I think that it can be.

the plane basis vectors) work, easy. Tweak the text window a bit,
for cosmetics, and start to add the symbolic expression code.
