Jonathan Westhues 6042fb3e0f Add transformed points and normals with a rotation (as well as a
translation; or equivalently, rotation about an arbitrary axis).
Those will be important for step and repeats, and for imported
parts.

Also fix a terrible memory corruption bug: I was freeing the remap
list after I loaded it from the file, but the code that put that
into the SS.group list made only a shallow copy.

Jonathan Westhues e11da119f0 Add point-line distance, point-plane distance, and point-on-circle
constraints. And generate the constraint equations for entities
(e.g., that our unit quaternions have magnitude one). Numerical
troubles there, but it sort of works. Also some stuff to draw
projection lines with projected constraints, and to auto-insert
more constraints as you draw.

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 6b264a6ba6 Add a convenience command to draw a rectangle (as four line
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.

Jonathan Westhues 853c6cb59c A big change, to add a concept of normals. These are "oriented
vectors", represented by unit quaternions. This permits me to add
circles, where the normal defines the plane of the circle.

Still many things painful. The interface for editing normals is not
so intuitive, and it's not yet clear how I would e.g. export a
circle entity and recreate it properly, since that entity has a
param not associated with a normal or point.

And the transformed points/normals do not yet support rotations.
That will be necessary soon.

Jonathan Westhues 60925e4040 A ~10x speedup in the solver. Simplify equations before evaluating
or taking partials (constant folding). Also keep a little hash
table to mark with params are used in each equation, in order to
quickly discard trivial partial derivatives. This is solving a
64x64 system in <20 ms. I suspect this is now much faster than
Sketchflat.

Slightly fake situation, though, since substitution solver has not
yet been written, and no partitioning. I'll do those next.

Jonathan Westhues 01cff278bd Include the remap lists (when we copy entities, that we used to
assign the new ids) in the saved file, and split the file load from
table stuff into its own function.

Jonathan Westhues 49ec1346d7 Add the first `derived' group, that generates entities based on
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.

Jonathan Westhues bfc7109e0c Standardize the behaviour of constraints, by assigning them a
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.

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

Jonathan Westhues 1331457928 Rough file/save for SolveSpace; that's all done from a single
table, relatively small code size. No user interface for it,
though.

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 0d3217c0df Rename some stuff in the IdList again. Rough in the file save
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.
