easy and useful. Also make the volume measurement use Message(),
and not a separate text window screen.
And make Edit -> Unselect All (Esc) clear the marks drawn to
indicate free parameters, since it clears all the other temporary
stuff drawn in the graphics window.

just LENGTH_EPS/1e2. At least in theory, that should still be
more than enough; all we need is for equal things to be equal
afterward, and even LENGTH_EPS/2 would guarantee that.

conversion factors in only one place, and clean up the
expression-parsing but removing all the copies of the same error

left-clicking always selects, and there's a special context menu
item to deselect. Also streamline the right-click behavior by
making that select the hovered item, and making all the context
menu items work on the selection.

selected entities, but cleared after dragging an unselected entity.
Marquee selection is select-only (not toggle), and "Select All"
replaces "Invert Selection". Left-click on nothing will clear the
selection.
Also add context menu entries for cut, copy, and paste.

does that, and adds a scale factor to that transformation (instead
of just mirroring, as before), but also:
* Replace the "import mirrored" mechanism with a scale factor,
which if negative corresponds to a reflection as well.
* Fix self-intersection checker to report a meaningful point
when edges are collinear.
* Don't blow an assertion on some types of invalid file;
instead provide a nice error message to the user.
* Clear the naked edges before each regen.
* Don't create zero-length line segments by snapping a line
segment's end to its beginning.

only in a workplane; but this means that plane sketches are
conveniently transformed from one plane to another.
Also tweak snap to grid to ignore unsnappable entities instead of
triggering an error, and to remove arbitrary limit on the number of
entities / comments that will be snapped.

[git-p4: depot-paths = "//depot/solvespace/": change = 2079]
because it can't be C2 continuous after splitting (since I'm
doing uniform splines only, and the parametrization changes). So
just knock everything down to cubic Beziers.
Also draw lines to indicate angle and origin when Ctrl+dragging to

previously a major bottleneck, and is now at least 10x faster for a
practical section.
And fix a horrible uninit memory bug in the triangle kd-tree stuff;
the split planes were apparently random. This would have slowed
things down, but not caused an incorrect result; except when it
ends up NaN, which is the reason I noticed.

everything even partially within that rectangle gets selected when
I release.
Also make deselecting a point deselect all coincident points too;
otherwise there now exist ways to select both coincident points,
which meant that it was impossible to deselect the lower one.
And fix text window to show selection info even if just constraints
are selected, seems more consistent.

one point to be dragged simultaneously. So now a dragged point
drags all the selected points and entities, and a dragged entity
drags its points (except for circles, which drag the radius).
This means that the number of forced points for the solver must now
be unlimited, and it is.
Also add commands to invert the selection within the active group,
and to select an edge chain starting from the current selection.
And redo the context menus a bit; still not great, but less
cluttered and more systematic.
[git-p4: depot-paths = "//depot/solvespace/": change = 2064]

to go ccw. So fix that.

also means that closed contours will get output as a single path
now, vs. one open path per Bezier segment before.
I've simplified the 2d/3d wireframe export targets somewhat; they
now support only Beziers, without an additional special case for
line segments. The performance penalty for that should not be worth
caring about, since that's infrequent.
And fix a memory leak in FindOuterFacesFrom(), fix ugly output of
filled triangles in PDF (because the line join style did bad things
on long skinny triangles), fix non-zero Z coordinates for exported
views or sections in DXF or STEP.

to assemble Beziers into outer and inner loops, and find those
loops made up of entities with filled styles. The open paths are
maintained in a separate list, and we assemble as many closed paths
as possible even when open paths exist.
This changes many things. The coplanar check is now performed on
the Beziers, not the resulting polygon. The way that the polygon is
used to determine loop directions is also modified.
Also fix the mouse behavior when dragging a point: drop it when the
mouse is released, even if it is released outside the window, but
don't drop it if the pointer is dragged out of and then back into
our window.
Also special-case SSurface::ClosestPointTo() for planes, for speed.

their endpoints.
Also change constraint solver matrix size to 1024, on the theory
that a power of two will generate better array indexing, and
replace fabs() with my own function that for some reason is
faster.
