This change comprehensively replaces the use of Microsoft-standard integer
and boolean types with their C99/C++ standard equivalents, as the latter is
more appropriate for a cross-platform application. With matter-of-course
exceptions in the Win32-specific code, the types/values have been converted
as follows:
QWORD --> uint64_t
SQWORD --> int64_t
DWORD --> uint32_t
SDWORD --> int32_t
WORD --> uint16_t
SWORD --> int16_t
BYTE --> uint8_t
BOOL --> bool
TRUE --> true
FALSE --> false
The following related changes are also included:
* Added C99 integer type definitions for Windows, as stdint.h is not
available prior to Visual Studio 2010
* Changed types of some variables in the SolveSpace class from 'int' to
'bool', as they actually represent boolean settings
* Implemented new Cnf{Freeze,Thaw}Bool() functions to support boolean
variables in the Registry
* Cnf{Freeze,Thaw}DWORD() are now Cnf{Freeze,Thaw}Int()
* TtfFont::Get{WORD,DWORD}() are now TtfFont::Get{USHORT,ULONG}() (names
inspired by the OpenType spec)
* RGB colors are packed into an integer of type uint32_t (nee DWORD), but
in a few places, these were represented by an int; these have been
corrected to uint32_t
The Valgrind tool can give a full accounting of what memory allocations
have yet to be free()d when the program exits. It is easier to find actual
memory leaks in the code if all non-leaked allocations are elided from that
accounting, which is most easily accomplished by free()ing them.
The "most" qualifier is there because some allocations are difficult/
impossible to free, as they are internal to libraries like OpenGL and Xft.
The best we can hope for is to cover all allocations made by SolveSpace
directly.
This function was returning ID{YES,NO,CANCEL}, which are specific to
Windows as return values for MessageBox(). These have been replaced with
SAVE_{YES,NO,CANCEL}, which we define ourselves.
String literals in C++ are implicitly typed as 'const char *', and with
this change, their const-ness is maintained when assigning them to
variables or passing them as arguments. This significantly cuts down the
number of warnings generated by the compiler.

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

whether the original lines should be kept and made construction, or
deleted.

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.

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.

conversion factors in only one place, and clean up the
expression-parsing but removing all the copies of the same error
message.

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.

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

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.

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.

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.

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.

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.

and I don't have the stuff to handle holes or multiple outer
contours in a single surface.

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.

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.

simplify use of the constraint solver in a library.
