Jonathan Westhues ce99217bbb Move colors and line widths for almost everything to the styles
mechanism. This gets filled in from some defaults, and stored in
the registry. The default styles do not get saved in the file, but
user-created styles (which aren't supported yet) do.

Jonathan Westhues ddf9364257 Add a separate display mesh and edge list; so if we're working with
a mesh than that's a copy, and if we're working with a shell then
it's the shell's triangulation.

Jonathan Westhues bc6bdfade8 Save the exact surfaces in the exported file, and import and
transform them for assembly.

Jonathan Westhues a4dc518a89 A monster change; move the parameter, entity, group, and constraint
tables from SolveSpace to their own class. This is intended to
simplify use of the constraint solver in a library.

Jonathan Westhues 71adc0bf54 Split ratpoly.cpp; now that contains only the mathematical stuff,
and curve.cpp and surface.cpp contain the rest.

Also get rid of the meshError stuff; will just use the nakedEdges
mechanism for that. And I won't run the interference test
continuously, have added a menu item for that.

Jonathan Westhues bb4b767e99 Tear everything apart, moving away from meshes and toward shells.
Add stubs for functions to perform Booleans, and get rid of mesh
stuff, including the kd tree accelerated snap to vertex (which
should not be required if the shell triangulation performs as it
should).

Also check that a sketch is not self-intersecting before extruding
it or whatever. This is dead slow, needs n*log(n) implementation.

Jonathan Westhues ebca6130ec Early attempts at rational polynomial surfaces. I can create one
from an extrusion, with piecewise linear trim curves for everything
(that are shared, so that they appear only once for the two
surfaces that each trims). No Boolean operations on them, and the
triangulation is bad, because gl seems to merge collinear edges.

So before going further, I seem to need my own triangulation code.
I have not had great luck in the past, but I can't live without it
now.

Jonathan Westhues 25ed4e1ef1 SPolyCurve (i.e., polynomial curve) vs. SPolygon got too confusing;
let's call those Beziers instead.

Jonathan Westhues 0e623c90c0 Generate the group's polygon from the exact curves, not from edges;
so now we've got the exact curve loops, with their direction
standardized so that we can tell which direction is out. We still
need the polygon in any case, since that's a convenient way to find
each curve's winding number.

And remove some more leftover code from mesh sweeps.

Jonathan Westhues 7b7d2f92e9 Add code to evaluate the volume of a mesh, thanks to the divergence
theorem; it's evaluated as a surface integral over each triangle.

And don't regenerate the emphasized edges unless we have to;
specifically, don't do it when the only dirty group is the
drawing group.

Jonathan Westhues cad77c9c47 Add routines to remove T intersections from the mesh, which are
introduced by the bsp routines. It's usually, though not always,
possible to generate a watertight mesh. The occasions where it's
not look ugly, floating point issues, no quick fix.

And use those to generate a list of edges where two different faces
meet, which I can emphasize for cosmetic reasons (and some UI to
specify whether to do that, and with what color).

And make the right mouse button rotate the model, since that was
previously doing nothing.

Jonathan Westhues 273339d5c4 Add TrueType font support to SolveSpace. This uses a modified
version of the code from SketchFlat, with all arbitrary limits
removed.

The TTF text is its own entity, and that entity includes the
font file basename and the text. That's an extra 128 bytes in the
entity, which is around a 50% increase, kind of a shame. It was
simple, though.

Jonathan Westhues 5a22982e05 Add sweeps. The user specifies a trajectory and a section, in two
separate groups. The section is swept normal to the trajectory,
producing a mesh. I'm doing the triangles only now, not copying
over any entities.

Also fix a bug in the PNG export; rows are 4-aligned, so that was
breaking when the width of the image wasn't divisible by four. Also
fix a bug in lathes, where it generated overlapping triangles for
one segment.

And change the groups to record both "this mesh", the contribution
due to the extrude/lathe/whatever, and the "running mesh", that we
get after applying the requested Boolean op between "this mesh" and
the previous group's "running mesh". I'll use that to make step and
repeats step the mesh too.

Jonathan Westhues 28e3f0abab Don't keep a dimension or group's user-entered numerical value as
an Expr *, since that complicates multiple units and also memory
management. Now it's just a double.

Jonathan Westhues 48612bde3d Add undo/redo. This saves the param guesses, constraints, groups,
and requests to a separate list. It's messy, because I have to make
a deep copy (e.g. of the remap list for the groups, or Expr *
stuff) of some things. Others (e.g. the polygon or mesh) will be
regenerated, so they should be discarded, but they must not get
double-freed.

In any case, works superficially. And fix a few memory leaks
unrelated to this, and remove some dead code.
