Jonathan Westhues 7b7d2f92e9 Add code to evaluate the volume of a mesh, thanks to the divergence
theorem; it's evaluated as a surface integral over each triangle.

And don't regenerate the emphasized edges unless we have to;
specifically, don't do it when the only dirty group is the
drawing group.

Jonathan Westhues 8fe910da4d Add feature to trace a point; so I can show the path that a
linkage traces out, and export the coordinates.

Jonathan Westhues 44795175ee A suggestion when we fail to converge or go singular.

Jonathan Westhues 49b6e9a74d Remove the back button from the text window, since I never used it.
And fix a bug; wasn't asking the user whether to save before
abandoning file when a new file was opened recent.

Jonathan Westhues 7622534b2a Make the piecewise linear stuff for cubics and quadratics adaptive,
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.

Jonathan Westhues dd23aa11a2 Make rotations default to 360/n degrees (uniform about a circle)
if no constraints set the rotation.

Jonathan Westhues 72d188619d Add a scale factor when exporting; the user specifies a number, and
all coordinates are divided by that number as we export.

And add functions to store a float in the registry. I'm using those
for the scale factor, and also to replace the crazy scaled integers
that I was using for light positions etc. before.

Jonathan Westhues cad77c9c47 Add routines to remove T intersections from the mesh, which are
introduced by the bsp routines. It's usually, though not always,
possible to generate a watertight mesh. The occasions where it's
not look ugly, floating point issues, no quick fix.

And use those to generate a list of edges where two different faces
meet, which I can emphasize for cosmetic reasons (and some UI to
specify whether to do that, and with what color).

And make the right mouse button rotate the model, since that was
previously doing nothing.

Jonathan Westhues 48c5018613 Add symmetric about line constraint. This applies only when locked
in a workplane, since it would otherwise be ambiguous.

Jonathan Westhues 273339d5c4 Add TrueType font support to SolveSpace. This uses a modified
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.

Jonathan Westhues 12942a74cf Add logic to remember imported files' relative filenames, and use
that to try to find them if we can't find them by absolute path.
This is intended to make everything still work if you copy an
entire directory tree of files that import each other.

Also add a mechanism to not paint the scene if we're not sure it's
consistent; otherwise got some crashes on startup. And disable both
text and graphic window when displaying a modal dialog, wasn't
doing that always.

Jonathan Westhues bc5b43de85 Split the BSP stuff off the mesh stuff, and the text screens
themselves of the text window utility functions.
