segments), add the toggle construction command, and color the lines
differently depending on what group you're in.
Also change dynamic memory stuff to use a Win32 heap for everything
(no malloc), and validate that often. I think I've seen it crash,
though I can't reproduce it.

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.
[git-p4: depot-paths = "//depot/solvespace/": change = 1695]
erased before redraw, which caused a bit of flicker on show. And
hide debug prints in solver.

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.
[git-p4: depot-paths = "//depot/solvespace/": change = 1692]
workplane: a free constraint works in three-space (e.g. true
distance), and a constraint in a workplane works in that plane
(e.g. projected distance). And make the solver go automatically,
though solver itself has lots of pieces missing.
[git-p4: depot-paths = "//depot/solvespace/": change = 1691]
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.
[git-p4: depot-paths = "//depot/solvespace/": change = 1687]
determine what goes in front (e.g. put a drawn line in front of the
reference plane, even if the z order would want the opposite), and
some tweaks to the mouse behaviour, and a function to modify
constraints like dimensions so that the are initially satisfied.
[git-p4: depot-paths = "//depot/solvespace/": change = 1681]
the label associated with a constraint. And that even works,
changes the length of the line.
[git-p4: depot-paths = "//depot/solvespace/": change = 1678]
and point-in-plane. These work, but the equation is still stupid,
solving everything at once and not substituting trivial equations.
[git-p4: depot-paths = "//depot/solvespace/": change = 1677]
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.
[git-p4: depot-paths = "//depot/solvespace/": change = 1672]
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.
[git-p4: depot-paths = "//depot/solvespace/": change = 1670]
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.
[git-p4: depot-paths = "//depot/solvespace/": change = 1668]
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]
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]
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.
[git-p4: depot-paths = "//depot/solvespace/": change = 1656]
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.
[git-p4: depot-paths = "//depot/solvespace/": change = 1653]
constraint solver drawing. I've started work on the user inteface,
which will be based around two windows: one with the graphical
sketch, and one command line. I've started to implement the command
line, no other work.
