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.
[git-p4: depot-paths = "//depot/solvespace/": change = 1769]
solid red or yellow. And add user interface to `hide' the faces
(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,
possibly different versions with different arg types.

more starting work on the selectable faces, and fiddling in an
attempt to remove dependencies when stuff gets deleted.

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.
[git-p4: depot-paths = "//depot/solvespace/": change = 1757]

are transformed by a rotation and translation, and appear in the
sketch; the transformation may be set with constraints.

recently opened files, that is saved in the registry and displayed
in a separate popup menu.
[git-p4: depot-paths = "//depot/solvespace/": change = 1752]
nicely. And to do that, I've added the user interface to show an
edit control in the text window.
[git-p4: depot-paths = "//depot/solvespace/": change = 1749]
so e.g. a new extrude starts in free space, which is likely what
you want. And default to an in-workplane group, and tweak the
display of workplanes.
[git-p4: depot-paths = "//depot/solvespace/": change = 1748]
and in the case of a singular Jacobian, report which constraints
can be removed to fix it. Also a mechanism to hover and select
entities and constraints from the text window.
[git-p4: depot-paths = "//depot/solvespace/": change = 1746]

plane lies in multiple triangles and choose the one with the
biggest normal magnitude (i.e., area) when testing normal
direction.
[git-p4: depot-paths = "//depot/solvespace/": change = 1745]
implement that. Also make solver work only between the first and
last visible group; earlier can just work from previous solve
result, and later don't matter.
There's some issues with the csg code; it will eventually produce
an open mesh, which is very bad. Not sure whether that's a logic
bug, or a numerical issue; still generating absurd triangles pretty
routinely.
[git-p4: depot-paths = "//depot/solvespace/": change = 1741]
polygon, not just triangles. This helps to avoid needless
splitting. Also test if an entire triangle got inserted in multiple
pieces; if yes, back things out, and just insert the triangle.
Also remove the extra partition stuff, since it didn't seem to help
consistently, and this does.
Still could do some better merging, in the case where an inserted
triangle does not get fully inserted, but we can find a better
triangulation than what the BSP naturally gives.
[git-p4: depot-paths = "//depot/solvespace/": change = 1739]
zero-area triangles, apparently. And make the number of line
segments used to approximate a triangle depend on its scale on
screen.
[git-p4: depot-paths = "//depot/solvespace/": change = 1738]
while building it. That may improve performance, by building a more
balanced tree and actually reducing splitting. Not dramatic
improvements, though; half the triangles for some parts, but no
change or slightly worse for others.
