Jonathan Westhues 8a70efed05 Make sliver triangle tests work on the minimum altitude, not on
area.

Jonathan Westhues a47a77c37c Back to opengl's tesselator for triangulation. I'll spend more time
writing mine later.

Jonathan Westhues 9b008ad1cd Check in a broken triangulation code (by stupid ear clipping),
which I will shortly revert. gl does a much better job, and I'll
have to spend more time to get something reasonable.

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 8969687904 Bits and pieces; option to not include original in step translates
and rotates, auto-constrain translates in active workplane, speed
up remap list search with a hash table, other stuff.

Jonathan Westhues 8498a99588 Add preliminary lathe (solid of revolution) support. I'm generating
just the mesh, no derived entities (but I suppose that I could turn
all points into circles).

And fix some bugs where equations didn't get unique IDs, and make
it possible to lock on to the group's workplane automatically, if
you press W while free in 3d with no workplane selected.

Jonathan Westhues 64c7a4e61b Fix bugs: problem drag-rotating normals with the mouse, a failure
to save our registry stuff (because we were calling exit() instead
of doing a PostQuitMessage()), and a misclassification of triangles
coplanar with the test surface, when the test surface contained
zero-area triangles.

Jonathan Westhues 6748160026 Add selectable faces, by associating an hEntity with the triangle's
metadata. And add point-on-face constraints to go with that. Still
needs some cleanup for the user interface.

Jonathan Westhues 04af0944bc Standardize naming of FromXxx (and XxxFrom) static methods to
create a `new' stack-allocated instance of an object; just From,
possibly different versions with different arg types.

Jonathan Westhues f803806029 Don't initialize the SEdges with ... = { ... }; use a special
function for that.

Jonathan Westhues 69eb2273ac Add color. Now each triangle has metadata, which are preserved in
csg ops; so the union of a red part and a blue part has both red
and blue faces. And some user interface to pick the color in the
text window.

The metadata also include a face, which will be an entity; I can
use that to constrain against. But none of that is yet implemented.

Jonathan Westhues 4d7ffc85f9 Make coplanar faces work properly, by implementing a 2d BSP on each
set of coplanar faces. The polygon count still gets stupid fast;
I'm thinking I can fix that by adding some extra test planes at the
top of the 3d BSP, to quickly cull out stuff that doesn't intersect
us.

Jonathan Westhues de46118324 Add code to extrude a triangle mesh, and to perform Boolean ops on
a triangle mesh in a BSP. That works, although it splits too often,
the initial triangulations are not good quality, and coplanar faces
are not yet handled. I'll do the coplanar thing tomorrow.

Jonathan Westhues 7c4d305895 Add polygon triangulation, by cheating. I'm using the gl tesselator
for that, and storing the triangles instead of rendering them
immediately. Not sure if that's smart; in theory could change from
implementation to implementation, but the results look much better
than I would get myself.

Jonathan Westhues e80328279e Rip out the boundary rep csg stuff. I'll redo that with a triangle
mesh approach.

Jonathan Westhues c4e1270e25 Add constructive solid geometry ops. These work to some extent, but
not very well; I'm doing a b-rep, where the boundaries are complex
polygons, and there's too many special cases. I should probably
replace this with a triangle mesh solution.

Jonathan Westhues 3cdbbb83b1 If a deletion makes it impossible to define other elements of the
sketch (e.g., a line whose length is constrained gets deleted, but
the constraint is left behind; or the point that's the origin for a
drawing group in plane gets deleted), then deleted the dependencies
too.

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.

a polygon, and to fill that polygon.
