before toggling construction.

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]

text screen selection info.

to go ccw. So fix that.
[git-p4: depot-paths = "//depot/solvespace/": change = 2062]
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.
[git-p4: depot-paths = "//depot/solvespace/": change = 2061]
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.

Also add user interface to specify fill color.

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.

Also fix piecewise linear tolerance when the export scale factor is
not equal to one; have to scale the chord tol along with that.

rewrite all URLs to solvespace.com, not www.solvespace.com, and get
rid of the nag screen that I just added because opening the website
with ShellExecute seems to freeze a bit on startup.

perspective and parallel projections. Add a snap grid, for points
and for text comments. Draw text comments in the plane of their
workplane if they have one, otherwise always facing forward.
And fix a few nasty bugs: the possibility of an extremely long
animation onto a workplane, accidental use of the wrong style line
width for constraints, misplaced text box in style screen for
default styles, other little stuff.

And fix two crashing bugs, embarrassing, both chasing null pointers.
[git-p4: depot-paths = "//depot/solvespace/": change = 2031]
formats, with the proper color and width. This may need a bit of
cleanup for stuff like the hidden line removal, which currently
loses the style.
Also fix a bug in the test for arcs of a circle. A second-order
Bezier with collinear control points really is an arc, but it's an
arc with infinite radius so stuff tends to blow up. So return false
for that one.
[git-p4: depot-paths = "//depot/solvespace/": change = 2030]
line width units, on-screen and export visibility. So now we can
use that to modify the default styles, or to create custom styles.
Also add code to draw fat lines, with round endcaps, since gl
doesn't do that.
Next we need some user interface to assign styles to entities, and
to make all the export file formats support the style attributes.
[git-p4: depot-paths = "//depot/solvespace/": change = 2029]
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.

size for EPS, etc.). This can either be fixed, with a given width
and height and offset, or automatic, by the left right bottom top
margins.
And draw nicer dimensions for length, with arrows and more
extension lines. Add code to trim those lines against the
(rectangular, axis-aligned) box that contains the actual number,
and use that (instead of the elliptical interpolation, which was
only approximately right) for diameter dimensions too.
[git-p4: depot-paths = "//depot/solvespace/": change = 2027]
surface's domain of u, v in [0, 1]. Cache the starting guess when
projecting a point into a ratpoly surface, to avoid brute force
searching for a good one every time. Split edges even if they
aren't quite inside the trim curve, since the trim boundaries are
pwl, not exact; unnecessary splits won't hurt, but failure to split
when necessary will. Make the triangulation code use a better (but
not perfect) epsilon, to avoid "can't find ear" failures on very
fine meshes.
And turn on compiler optimization! I had somehow forgotten about
that, and it's a ~2x improvement.

to get a big movement without realizing (especially with a parallel
projection of the part).
[git-p4: depot-paths = "//depot/solvespace/": change = 2021]
(in my case, a SpaceNavigator). I can transform the view of the
part, or transform a part in an assembly.
Also fix up mouse wheel input, so that it works even if it comes in
chunks of less than 120 units.
[git-p4: depot-paths = "//depot/solvespace/": change = 2019]
steps in thisShell or thisMesh, and then let the Boolean proceed as
usual. If everything works, then this is equivalent. And it's less
code, and it makes stuff like stepping the step and repeat work.
Also begin to work on line/entity/constraint styles, but no real
work yet.
[git-p4: depot-paths = "//depot/solvespace/": change = 2018]
shell when the current group has thisMesh and thisShell empty was
broken, since rotate or step and repeat groups don't use those.
So force something (doesn't matter what) into thisMesh or thisShell
in a step and repeat group, to make sure it always gets
recalculated and displayed. Ugly fix though.
[git-p4: depot-paths = "//depot/solvespace/": change = 2017]
a method that works on the piecewise linear segments, and then
refines any intersections that it finds by Newton's method. So now
I support cubics too, and circle-circle intersections, and the code
is much simpler.

for the vector font.
A little ugly; it needs some kind of line style (color or width) to
distinguish those lines from the real geometry in the exported

plane square with side length one.
So modify the SBspUv tests to take a surface, and measure distance
linearized in that surface. That fixes at least one
mis-classification bug, and doesn't seem to break anything.

thisMesh are empty), then display the previous group's instead.
This saves us re-triangulating the shell (or recalculating the
edges of a triangle mesh) every time our group gets regenerated,
which was horribly slow.
[git-p4: depot-paths = "//depot/solvespace/": change = 2004]
Otherwise, we might merge in ways that make things slower (because
the bboxes aren't as tight) or less robust (because the
intersection needs to be split in more places, and that might fail).
