Jonathan Westhues c934737d9e Add a function to combine vertices while tesselating the polygon,
so that OpenGL can fill self-intersecting polygons.

Jonathan Westhues 1bf7e3deaf Add an ExprVector class, for a 3-vector whose members are
expressions. That simplifies a few things considerably. And some
little UI tweaks.

Jonathan Westhues 9b1b255e85 Now I can display the edit control in the graphics window, and edit
the label associated with a constraint. And that even works,
changes the length of the line.

Jonathan Westhues 2926fa95d9 Start to add some constraint stuff. I now have point-coincident,
and point-in-plane. These work, but the equation is still stupid,
solving everything at once and not substituting trivial equations.

Jonathan Westhues cc03fe40aa Big structural change; eliminate the Point type in SolveSpace. The
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.

Jonathan Westhues 2f4a3917c5 Add functions to deep-copy Exprs, for those generated from user
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.

Jonathan Westhues 1fa7865024 Add a little parser, that takes a string and generates and Expr *
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.

Jonathan Westhues 22302dca7a Now I can add a constraint (a length), and it's displayed
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.

Jonathan Westhues 094e10204d Make the points locked in 2d csys (expressed as two parameters, for
the plane basis vectors) work, easy. Tweak the text window a bit,
for cosmetics, and start to add the symbolic expression code.

Jonathan Westhues 6c63d9c8cb Get rid of the command line from the text window; we'll say that's
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.

Jonathan Westhues a7fa89c2cc Check in some SolveSpace stuff, even though I didn't make much
progress. I want to change the sketch.h stuff fairly significantly,
I think, before proceeding.
