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.

on-screen, and I can drag the label. That's progress. Also
implement a bunch of untested expression stuff, since I'll need
that for the values of the dimensions, for example.

the plane basis vectors) work, easy. Tweak the text window a bit,
for cosmetics, and start to add the symbolic expression code.
[git-p4: depot-paths = "//depot/solvespace/": change = 1667]
can use the high bits as an "import ID" for imported parts, for
hierarchy (that retains parametric capabilities).
Implement enought that I can draw a datum point or a line segment,
and drag points around in three-space. Still so much to do.

just for display, and any text entry will happen via some floating
text box, same as entering a dimension on the sketch.
Add the hover and selection mechanism, which now seems to work.
Still not clear how to do imported parts, for assemblies and
hierarchy. The handle formats may still have to change.
[git-p4: depot-paths = "//depot/solvespace/": change = 1662]
and I am assuming that many more operations will require lookups in
the IdList<>.
Add code to represent and draw a 2d coordinate system. The origin
is described by a point, and the orientation by a quaternion. So
now it does the same thing before, and draws the reference planes,
but with a lot more lines of code.
[git-p4: depot-paths = "//depot/solvespace/": change = 1658]
draw planes that I will use to do the datum planes. Still haven't
settled upon the request/entity/group structure, and that's the
dependency before doing much real.

the text window every time we refresh the graphics window, because
that's slow. Use classes instead of structs for everything; I don't
understand the template handling for structs. And implement the
IdList, which I will try to use in many places.
[git-p4: depot-paths = "//depot/solvespace/": change = 1655]
and add some (non-functional) menus to the graphics window. Start
to rough in some data structures to hold the sketch. No real work
yet, though.
