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 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 01885736e6 Fix my rotation-matrix-to-quaternion code: it broke when the
diagonal elements of the matrix summed to -1. Now it's ugly, but I
think that it's correct. And add a command to flip the view to the
other side, which is what started my problems. And tweak display of
H and V and M for constraints: put them in the constraint plane, so
that they're stationary as you rotate around.

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

Jonathan Westhues 1f77024771 Add an equal length constraint for line segments.

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.

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

Jonathan Westhues 9c2a8a08dc Drastic changes to the handle structure; that's now just 32 bits,
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.

Jonathan Westhues 19c6be530f Bits and pieces of SolveSpace; zoom works now, and some stuff to
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.

Jonathan Westhues f201d52247 Add hyperlink and colour support to the text window. Don't redraw
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.

Jonathan Westhues e426fe8a53 Start to add OpenGL support to SolveSpace, for the graphical view.
I've got the user interface to pan and rotate an object, more or
less works.
