Jonathan Westhues 328a946cc4 Add a diameter constraint, and add a `distance' entity that I can
remap when I copy circle entities, in order to make the radius
numerical somehow (analogy with the POINT_ and NORMAL_XFRMD) thing.

Jonathan Westhues d048946adc Fix some stupid bugs introduced with the new representation of
workplanes. And fix up our polygon normals, so that everything gets
shaded correctly (and so that later we can generate our STL files
with correct normals).

Jonathan Westhues 30636a6f29 Make the extrude command do a bit more; now I generate all the
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.

Jonathan Westhues 498ffd07ea Add symmetric and at midpoint constraints. The symmetry constraint
turned out straightforward, in great part because the planes are
workplanes (6 DOF, represented by a unit quaternion and a point),
and therefore make it easy to get a vector in the plane, as well as
a normal.

And on that subject, replace the previous hack for parallel vector
constraints with a better hack: pivot on the initial numerical
guess, to choose which components of the cross product to drive to
zero. Ugly, but I think that will be as robust as I can get.

Jonathan Westhues 70bf14530d Add point on line constraints, in 2d and 3d. The 3d equations do
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.

Jonathan Westhues 15476d4732 A great renaming. 2d coordinate systems are now called workplanes,
and the associated entities are now just points.

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

Jonathan Westhues a7cec38656 Add code to assemble the piecewise linear segments in a group into
a polygon, and to fill that polygon.

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 181e50f1d9 Add routines to draw a vector font (public domain Hershey Simplex
font, not bad). Use that to label the planes now.
