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.

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.

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.

constraint, so that we can export that too. This includes the lines
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
file.

problem or a tendency to generate backwards edges or both, need to
debug that. But it generates the curve, and begins to work.
And change the edge classification. Now instead of testing for
point-on-surface using the results of the raycasting, test for
point-on-surface as a separate step. That stops us from picking up
the additional numerical error from the surface-line intersection,
which may be significant if the ray is parallel or almost parallel
to the surface.

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.

little test app that links against it. I still need to polish a few
things, but this is more or less as it should be.

tables from SolveSpace to their own class. This is intended to
simplify use of the constraint solver in a library.

the fundamental geometric stuff in XxxBase. Next I hope to make the
constraint solver use only the XxxBase types.

so now we've got the exact curve loops, with their direction
standardized so that we can tell which direction is out. We still
need the polygon in any case, since that's a convenient way to find
each curve's winding number.
And remove some more leftover code from mesh sweeps.
[git-p4: depot-paths = "//depot/solvespace/": change = 1897]
piecwise linear segments. These are piecewise linear approximated
for display, and currently for the mesh too, but that's the first
step to replace the mesh with exact curved surfaces.

corresponding to each param from the Jacobian, and see if it loses
rank. If it does then that one was important, so it's bound. Then
display a big blue square around its point until the next normal
solve.

linear segments to generate, irrespective of the chord tolerance.
That used to be hard-coded, and it needs to be small enough to
avoid lags while working interactively, but I also need to export
fine geometry.
[git-p4: depot-paths = "//depot/solvespace/": change = 1857]
lets us export open curves, if the user drew them that way.
Also increase the limits on how many pwls we will generate for a
single curve.
[git-p4: depot-paths = "//depot/solvespace/": change = 1854]
based on a chord tolerance. And rewrite the pwl circles to work
against a chord tolerance too (which they really were doing before,
but in funny units).
Also make "assemble" combine type do a union after interference
checking; was previously just copying, which meant that coplanar
faces could break subsequent operations.
And make right-clicking effectively toggle shift key, instead of
forcing it on; so you can pan or rotate with either right or middle
button.

version of the code from SketchFlat, with all arbitrary limits
removed.
The TTF text is its own entity, and that entity includes the
font file basename and the text. That's an extra 128 bytes in the
entity, which is around a 50% increase, kind of a shame. It was
simple, though.
[git-p4: depot-paths = "//depot/solvespace/": change = 1814]
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]
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).
