Also reshuffle some options in the configuration screen, to put all
the stuff relating to exports together.

And update the version number to 1.7, in preparation for the next
release.

radius, instead of letting us choose automatically, and specify
whether the original lines should be kept and made construction, or
deleted.

default. Same meaning, but less confusion.

to draw those, and hit test with the mouse, and display tool tips
when the user hovers with the mouse. Also, underline links only
when they're hovered, and not otherwise.
And add a separate menu option to align the view to the active
workplane, vs. activating the active group's workplane, and
remap the bottom two graphics window toolbar icons to that and
"nearest iso view" instead of draw in 2d/3d, since people tended
to click on those without understanding and cause trouble.
And by default, we force a parallel projection; so the factory
default camera tangent is now 0.3, not 0.
[git-p4: depot-paths = "//depot/solvespace/": change = 2131]
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.

rotation. Also clean up the handling of units, by putting the
conversion factors in only one place, and clean up the
expression-parsing but removing all the copies of the same error
message.
[git-p4: depot-paths = "//depot/solvespace/": change = 2093]
the same plumbing as the 2d vector output.
Also fix piecewise linear tolerance when the export scale factor is
not equal to one; have to scale the chord tol along with that.
[git-p4: depot-paths = "//depot/solvespace/": change = 2053]
instead of tying that to whether the shaded model is shown. And
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.
[git-p4: depot-paths = "//depot/solvespace/": change = 2044]
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.
[git-p4: depot-paths = "//depot/solvespace/": change = 2037]
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.
[git-p4: depot-paths = "//depot/solvespace/": change = 2028]
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]

building the loops, and don't show force-hidden entities when that
entity gets copied.

xyz point that I subtracted off had been refined to lie exactly on
our edge's curve, and the uv point that I started with had not. So
normals got randomly screwed up.
[git-p4: depot-paths = "//depot/solvespace/": change = 1978]
and their holes into their own advanced faces. So a single surface
with multiple outer contours generates multiple advanced faces.
Also turn the default chord tol down to 1.5 pixels, seems more
likely to make the exact surface Booleans work.
[git-p4: depot-paths = "//depot/solvespace/": change = 1975]
feared. Though I don't have rational surfaces or curves going yet,
and I don't have the stuff to handle holes or multiple outer
contours in a single surface.
[git-p4: depot-paths = "//depot/solvespace/": change = 1974]
check, hide the coordinate axes at the origin when normals are
hidden (but still show the coordinate axes at the bottom left of
the screen), and report point-line distance when a point and a line
are selected.

pairs) edges when just testing for interference.
[git-p4: depot-paths = "//depot/solvespace/": change = 1967]
separate polygon of coincident (with same or opposite normal)
faces; I instead test all the edges against the other shell, and
have extended the classify-against-shell stuff to handle those
cases.
And the normals are now perturbed a bit numerically, to either side
of the edge, to distinguish tangency from a coincident surface.
This seems to work fairly well, although things still tend to fail
when the piecewise linear tolerance is too coarse.
[git-p4: depot-paths = "//depot/solvespace/": change = 1964]
can show edges for both meshes and shells, and export them and
hidden line remove and all the usual stuff.
And fix the zoom to fit on startup, so that it considers hidden
entities too. That avoids the problem where things get generated at
stupid chord tolerance because no entities were visible and the
mesh of course did not yet exist.
[git-p4: depot-paths = "//depot/solvespace/": change = 1961]
exact surface shells. And add interference checking; I'll be lazy
and just do that on the meshes, by modifying the self-intersection
tester to ignore coplanar triangles (since that can happen in an
assembly).
[git-p4: depot-paths = "//depot/solvespace/": change = 1958]
a mesh than that's a copy, and if we're working with a shell then
it's the shell's triangulation.
[git-p4: depot-paths = "//depot/solvespace/": change = 1957]
a grid of quads, with adaptive spacing. The quads that lie entirely
within the trim polygon are triangulated and knocked out from the
polygon, and then the polygon is triangulated.
That works okay, though rather slow. But there are issues with
surfaces of revolution that touch the axis, since they end up with
a singularity. That will require some thought.
[git-p4: depot-paths = "//depot/solvespace/": change = 1951]
tables from SolveSpace to their own class. This is intended to
simplify use of the constraint solver in a library.
[git-p4: depot-paths = "//depot/solvespace/": change = 1942]
our specified section plane; we then split them according to the
start and endpoints of each STrimBy, using de Castejau's algorithm.
These sections get projected (possibly in perspective, which I do
correctly) into 2d and exported.
Except, for now they just get pwl'd in the export files. That's the
fallback, since it works for any file format. But that's the place
to add special cases for circles etc., or to export them exactly.
DXF supports the latter, but very painfully since I would need to
write a later-versioned file, which requires thousands of lines of
baggage. I'll probably stick with arcs.
[git-p4: depot-paths = "//depot/solvespace/": change = 1936]
and curve.cpp and surface.cpp contain the rest.
Also get rid of the meshError stuff; will just use the nakedEdges
mechanism for that. And I won't run the interference test
continuously, have added a menu item for that.
[git-p4: depot-paths = "//depot/solvespace/": change = 1934]
triangle join. And add controls to show and hide the solid model
edges (independently of the shaded mesh), and to suppress the
shaded triangles from SVG/EPS output.
[git-p4: depot-paths = "//depot/solvespace/": change = 1932]
export. So I calculate lighting for each triangle in the mesh, make
a BSP, and then traverse it in-order and output those as SVG or
EPS. And I test edges against the mesh, removing those portions of
the edge that overlap a triangle in front of them (using the
kd-tree to accelerate).
[git-p4: depot-paths = "//depot/solvespace/": change = 1931]
use that for surface-line intersections. That has major problems
with the heuristic on when to stop and do Newton polishing.
There's also an issue with all the Newton stuff when surfaces join
tangent.
And update the wishlist to reflect current needs.
[git-p4: depot-paths = "//depot/solvespace/": change = 1925]
fix convergence tolerance so that points projected into a rational
polynomial surface end up much closer than LENGTH_EPS.
