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 222007f3d8 Oops, make path relative routine was broken when the filenames
shared a prefix (/path/abc.slvs, /path/abcdef.slvs).

Jonathan Westhues 4afc881bf2 Add a command to create an arc that's tangent to two line segments.
This was possible before (by drawing everything explicitly), but
now it's easy.

Jonathan Westhues 7cf0deb9f4 Reassign the keyboard shortcuts so that the constraints don't all
start with Shift, since that's hard to type.

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 b2f2f90a27 Add DXF export. The complexity comes from all the different ways to
specify the plane from which we want to grab the triangles. Shared
edges are then removed with the same code used to check for
watertight meshes, and the remaining edges are assembled into
polygons.

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 fd4abd5519 Add a perpendicular constraint; identical to constraining a ninety
degree angle, but shows with a right angle symbol instead of a
numerical angle you can edit.

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

area.

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 a31782e1ea If any equations are soluble in a single variable, then handle them
separately, even before doing the rank test. In some cases, that's
a huge speedup.

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 a5189f7f1a Make step and repeats step the mesh, as well as the entities. This
requires new entitiy types for the faces, by translation or by
axis-angle rotation.

Jonathan Westhues 5a22982e05 Add sweeps. The user specifies a trajectory and a section, in two
separate groups. The section is swept normal to the trajectory,
producing a mesh. I'm doing the triangles only now, not copying
over any entities.

Also fix a bug in the PNG export; rows are 4-aligned, so that was
breaking when the width of the image wasn't divisible by four. Also
fix a bug in lathes, where it generated overlapping triangles for
one segment.

And change the groups to record both "this mesh", the contribution
due to the extrude/lathe/whatever, and the "running mesh", that we
get after applying the requested Boolean op between "this mesh" and
the previous group's "running mesh". I'll use that to make step and
repeats step the mesh too.

Jonathan Westhues ae566f0380 Link against libpng and zlib, and use that to export graphics;
basically just a screenshot, get the image from the framebuffer.

Jonathan Westhues 3b4aa2c2b2 Little fixes for units display, and change file format to binary
(even though it's still a text file), to avoid CRLF issue.

Jonathan Westhues b284baffce Treatment of numerical faces was screwy, exporting stuff in numXXX.
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.

Jonathan Westhues 9bba9425be Add a special constraint type for comments; no equations, just
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).

Jonathan Westhues 650e9db150 Add more measurement information about the selection. And remove
menu items for some features that I suppose I won't add, and fix
some bugs.

Jonathan Westhues 8498a99588 Add preliminary lathe (solid of revolution) support. I'm generating
just the mesh, no derived entities (but I suppose that I could turn
all points into circles).

And fix some bugs where equations didn't get unique IDs, and make
it possible to lock on to the group's workplane automatically, if
you press W while free in 3d with no workplane selected.

Jonathan Westhues ab44c24cfc Major speedups, mostly by playing nicer with OpenGL; batch things
up more. Also change from stupid linear search lists to sorted
binary search lists, remove a stupid bug where I double-generated
entities, and don't do the triple drawing of entities (since
offsets on the Z buffer were doing the same job already).

Jonathan Westhues 48612bde3d Add undo/redo. This saves the param guesses, constraints, groups,
and requests to a separate list. It's messy, because I have to make
a deep copy (e.g. of the remap list for the groups, or Expr *
stuff) of some things. Others (e.g. the polygon or mesh) will be
regenerated, so they should be discarded, but they must not get
double-freed.

In any case, works superficially. And fix a few memory leaks
unrelated to this, and remove some dead code.

Jonathan Westhues ea6db67c7d Improve convergence of constraints involving parallel vectors, by
using the initial numerical guess of whichever vector is already
known to choose our projection planes.

And add a mechanism to defer showing the text window or
regenerating, in order to simplify dependencies on valid actives.
Also yes/no/cancel when about to abandon an unsaved file, and a
bugfix when rotating a rot/trans point.
