and point-in-plane. These work, but the equation is still stupid,
solving everything at once and not substituting trivial equations.

points are now entities like any others; so a line segment request
will generate three entities, the line segment and its endpoints. I
think that's cleaner.
When I do step and repeats (and imports, and other similar), I'll
need a consistent way to assign those entity ids. That assignment
must not change if the sketch is edited. I don't have a clean way
to do that; best thought right now is to keep a record of what maps
have been used previously, and not pick a new map as long as it's
possible to use one that was used previously.
This all means that more crap gets pushed in to the Entity
structure, so that they can keep track of what solver variables
define them. Still seems better, though. I'm closer to ready
to start solving.

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.

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

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]
progress. I want to change the sketch.h stuff fairly significantly,
I think, before proceeding.
[git-p4: depot-paths = "//depot/solvespace/": change = 1657]
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.
