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.

same orientation constraint is applied; this makes convergence
easy. And don't hover faces or constraints while dragging
something.
[git-p4: depot-paths = "//depot/solvespace/": change = 1798]
that perspective in the gl matrices, and also everywhere that I
check mouse pointer positions against the model, and for the zoom
to fit.
[git-p4: depot-paths = "//depot/solvespace/": change = 1796]
point-line distance equal to line segment length. These are
available in both normal and projected versions, with fancy display
for all of these.

an Expr *, since that complicates multiple units and also memory
management. Now it's just a double.

axis of rotation numerically, so that the associative thing breaks,
and then it also wasn't saving the point on the axis in the file,
so that snapped back to (0, 0, 0) on reload. Now it goes off the
hEntity for a point on the axis and a vector in its direction.
[git-p4: depot-paths = "//depot/solvespace/": change = 1790]
So fix that, and now I can simplify what's exported for an entity.
And add an extra measurement (face-face distance/angle), and some
other little stuff.
[git-p4: depot-paths = "//depot/solvespace/": change = 1789]
user-visible text. And make points hoverable/selectable even when
GW.showPoints is false, and zoom to fit before regenerating on file
open, because then we're at the right zoom level (and will use the
right pwl tolerance).
[git-p4: depot-paths = "//depot/solvespace/": change = 1788]

up remap list search with a hash table, other stuff.
[git-p4: depot-paths = "//depot/solvespace/": change = 1786]
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.
[git-p4: depot-paths = "//depot/solvespace/": change = 1780]
up more. Also change from stupid linear search lists to sorted
binary search lists, remove a stupid bug where I double-generated
entities, and don't do the triple drawing of entities (since
offsets on the Z buffer were doing the same job already).
[git-p4: depot-paths = "//depot/solvespace/": change = 1776]
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.
[git-p4: depot-paths = "//depot/solvespace/": change = 1775]
BSP stuff works. The failures are reported with red stripes and no
depth buffering, and in a message in the text window.
Also improve convergence of point-on-line constraints, and don't
write triangles to export files with limited precision, because
that was making the coplanar tests fail.
[git-p4: depot-paths = "//depot/solvespace/": change = 1774]
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.
[git-p4: depot-paths = "//depot/solvespace/": change = 1773]
using the initial numerical guess of whichever vector is already
known to choose our projection planes.
And add a mechanism to defer showing the text window or
regenerating, in order to simplify dependencies on valid actives.
Also yes/no/cancel when about to abandon an unsaved file, and a
bugfix when rotating a rot/trans point.

becomes dirty when the user makes a change, and only the dirty
groups get solved. That's a huge effective speedup.
Also add delete function for groups. That has an interesting issue;
it actually ends up recursing on GenerateAll(), since GenerateAll()
calls ClearSuper(), ClearSuper() might need to recreate a group (if
all the groups were deleted), and that would activate the group,
which calls GenerateAll. The right solution is probably a deferred
execution mechanism, where you can schedule something to happen
before we go idle, but not do it right now.
[git-p4: depot-paths = "//depot/solvespace/": change = 1771]
in one place. And remove the ability to disable the solver, since
that's unlikely to be anything but confusing (and in any case, was
badly implemented). This is in preparation for selective solving,
of only the dirty groups.

(i.e., to make them unselectable), defaulting to hidden in
everything except extrudes or imports.
[git-p4: depot-paths = "//depot/solvespace/": change = 1768]
metadata. And add point-on-face constraints to go with that. Still
needs some cleanup for the user interface.

create a `new' stack-allocated instance of an object; just From,

case where you bolt a triangle onto a convex poly, and both
remaining edges of the tri are coincident with the neighbours from
the poly. That was a big source of zero-area triangles.
And tweak some colors a bit.
[git-p4: depot-paths = "//depot/solvespace/": change = 1758]
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.
