A new button is added, "Show/hide outline of solid model".
When the outline is hidden, it is rendered using the "solid edge"
style. When the outline is shown, it is rendered using the "outline"
style.
In SolveSpace's true WYSIWYG tradition, the 2d view export follows
the rendered view exactly.
Moreover, shell edges are not rendered anymore, since there is not
much need in them anymore and not drawing them lessens the overlap
between various kinds of lines, which already includes entities,
solid edges and outlines.
This results in massive performance improvements for hit testing.
Files with very large amounts of entities (e.g. [1]) inflict
a delay of several seconds between moving the pointer and
highlighting an entity in commit HEAD^^^, whereas in this commit
the delay is barely perceptible.

Scoped "Zoom to Fit" is convenient for working on large models.
I (whitequark) have considered a separate shortcut, but its
usefulness is unclear and in any case it can be easily added
if desired.
Before this commit, a single chord tolerance was used for both
displaying and exporting geometry. Moreover, this chord tolerance
was specified in screen pixels, and as such depended on zoom level.
This was inconvenient: exporting geometry with a required level of
precision required awkward manipulations of viewport. Moreover,
since some operations, e.g. mesh watertightness checking, were done
on triangle meshes which are generated differently depending on
the zoom level, these operations could report wildly different
and quite confusing results depending on zoom level.
The chord tolerance for display and export pursue completely distinct
goals: display chord tolerance should be set high enough to achieve
both fast regeneration and legible rendering, whereas export chord
tolerance should be set to match the dimension tolerance of
the fabrication process.
This commit introduces two distinct chord tolerances: a display
and an export one. Both chord tolerances are absolute and expressed
in millimeters; this is inappropriate for display purposes but
will be fixed in the next commits.
After exporting, the geometry is redrawn with the chord tolerance
configured for the export and an overlay message is displayed;
pressing Esc clears the message and returns the display back to
normal.
Instead, grab it from hoveredRow, since almost always (with only one
exception) this is where the edit control has to be shown.
This makes it much easier to adjust views, e.g. add a new editable
field in the middle of configuration view, because it's not necessary
to manually change and test all the indexes below the row being
changed.
Additionally, it removes a lot of awkward and opaque row calculations.
This setting is generally useful, but it especially shines when
assembling, since the "same orientation" and "parallel" constraints
remove three and two rotational degrees of freedom, which makes them
impossible to use with 3d "point on line" constraint that removes
two spatial and two rotational degrees of freedom.
The setting is not enabled for all imported groups by default
because it exhibits some edge case failures. For example:
* draw two line segments sharing a point,
* constrain lengths of line segments,
* constrain line segments perpendicular,
* constrain line segments to a 90° angle.
This is a truly degenerate case and so it is not considered very
important. However, we can fix this later by using Eigen::SparseQR.
This removes the arbitrary 64 byte restriction (which effectively
limits us to as little as 16 Unicode characters with CJK encodings),
makes classes smaller, and is easier to use.
As a consequence of making the length of all ex-NameStr fields
unbounded, all functions that returned a buffer derived from those
were changed to return std::string. Then, functions that are
contextually similar to the ones described above were changed
to return std::string. Then, functions that now happened to mostly
take an std::string argument converted to a C string were changed
to accept std::string.
This has produced a bit of churn, but is probably for the better.
Now it is possible to give non-ASCII names to groups
as well as see non-ASCII filenames of imported files.
In the future this makes localization possible.
This works for LTR languages, such as European and CJK,
but not RTL such as Arabic. Does Arabic even exist in
monospaced form? I have no idea.
Almost all construction requests are lines, and allowing to
draw them as construction obviates the need to select them one
by one afterwards to convert them. Also, it removes the "not closed
contour" error message, which is a nice usability improvement.
This is equivalent to adding a constraint, then making it a reference.
The benefits are that:
* it's quicker;
* it avoids having an over-constrained system, with an associated
angry red flash and a regeneration delay.
The latter in particular is a very substantial usability improvement.
The reference distance command is useful most of the time,
but the reference angle one is also added for consistency.
Some extra code is necessary to determine that the back faces
should not be drawn in red for transparent solids. It is expected
that the user will first ensure that the shell is watertight
and then set the opacity; back faces are still drawn if
the opacity is exactly 1.
The savefile format is changed backwards-compatibly by stashing
the alpha value in uppermost byte of 4-byte hex color value
in Surface and Triangle clauses. The existing files have 00
in the high byte, so RgbColor::FromPackedInt treats that
as "opaque".
In principle, GTK3 is the way forward, and GTK2 is officially
deprecated, though still maintained. In practice however, GTK3
is often unbearably buggy; e.g. on my system, combo boxes
don't ever roll up in GTK3 windows. So I have added support
for both.
This required a few minor changes to the core, namely:
* GTK wants to know beforehand whether a menu item is a check
menu item or a regular one.
* GTK doesn't give us an easy way to execute something after
any event is processed, so an explicit idle timer is added.
This is a no-op on Win32.
* A few function signatures were const'ed, since GTK expects
immutable strings when converting to Glib::ustring.
The SolveSpace top-level directory was getting a bit cluttered, so
following the example of numerous other free-software projects, we move the
main application source into a subdirectory and adjust the build systems
accordingly.
Also, got rid of the obj/ directory in favor of creating it on the fly in
Makefile.msvc.
