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.
possible. This replaces all of the color-coded links, that I liked
but that were nonstandard.
Also rip out the old sweep and helical sweep UI; that was disabled,
but the code was still present.
And fix dependencies in makefile, since textwin.cpp depends on the
icons now.

and that I put the characters in a two-dimensional grid in the
texture (since one-dimensional strip gets wider than the hardware
supports).

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.

code. This is now drawn using gl, and the bitmap font (both there
and in the graphics window) is drawn from a texture from a static
table, not from the Win32 functions, since that's ~1000x faster.
So this adds a tool to generate that table. With luck that will
also fix my font issues under WINE, which won't have to render the
TTF itself.
Still needs some cleanup, and to make all the cosmetic improvements
that I want.

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.
[git-p4: depot-paths = "//depot/solvespace/": change = 2007]
according to the user's preference. I templated the housekeeping
stuff for Boolean operations and step and repeat, so it's
relatively clean.
Still need to add the stuff to make a mesh vertex-to-vertex, and to
export sections of a mesh.

simplify use of the constraint solver in a library.

the same precedence as sqrt. Add the code to find naked edges, and
draw them highlighted on the model. And make the direction of trim
curves consistent, always ccw with normal toward viewer; so there's
no need to fix the directions before triangulating.
[git-p4: depot-paths = "//depot/solvespace/": change = 1903]
is O(n^2), not perfectly robust, and the bridge-finding code is
particularly bad. But it works, triangulates, and shouldn't ever
generate zero-area triangles like gl does.
[git-p4: depot-paths = "//depot/solvespace/": change = 1900]
from an extrusion, with piecewise linear trim curves for everything
(that are shared, so that they appear only once for the two
surfaces that each trims). No Boolean operations on them, and the
triangulation is bad, because gl seems to merge collinear edges.
So before going further, I seem to need my own triangulation code.
I have not had great luck in the past, but I can't live without it
now.
[git-p4: depot-paths = "//depot/solvespace/": change = 1899]
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.

check mouse pointer positions against the model, and for the zoom

GW.showPoints is false, and zoom to fit before regenerating on file

right pwl tolerance).

solid red or yellow. And add user interface to `hide' the faces
(i.e., to make them unselectable), defaulting to hidden in
everything except extrudes or imports.
[git-p4: depot-paths = "//depot/solvespace/": change = 1768]

needs some cleanup for the user interface.

csg ops; so the union of a red part and a blue part has both red
and blue faces. And some user interface to pick the color in the
text window.
The metadata also include a face, which will be an entity; I can
use that to constrain against. But none of that is yet implemented.
[git-p4: depot-paths = "//depot/solvespace/": change = 1757]
a triangle mesh in a BSP. That works, although it splits too often,
the initial triangulations are not good quality, and coplanar faces
are not yet handled. I'll do the coplanar thing tomorrow.

for that, and storing the triangles instead of rendering them
immediately. Not sure if that's smart; in theory could change from
implementation to implementation, but the results look much better
than I would get myself.
[git-p4: depot-paths = "//depot/solvespace/": change = 1733]
not very well; I'm doing a b-rep, where the boundaries are complex
polygons, and there's too many special cases. I should probably
replace this with a triangle mesh solution.

shaded correctly (and so that later we can generate our STL files
with correct normals).
[git-p4: depot-paths = "//depot/solvespace/": change = 1706]
faces of the polyhedron. And shade the faces when I draw them, and
fix up our projection matrix so that the depth testing works
properly.
[git-p4: depot-paths = "//depot/solvespace/": change = 1703]
turned out straightforward, in great part because the planes are
workplanes (6 DOF, represented by a unit quaternion and a point),
and therefore make it easy to get a vector in the plane, as well as
a normal.
And on that subject, replace the previous hack for parallel vector
constraints with a better hack: pivot on the initial numerical
guess, to choose which components of the cross product to drive to
zero. Ugly, but I think that will be as robust as I can get.
[git-p4: depot-paths = "//depot/solvespace/": change = 1699]
not have much motivation behind them, but they seem to work. And
make sure that we don't solve multiple times without repainting in
between, and tweak the text window a bit more.
[git-p4: depot-paths = "//depot/solvespace/": change = 1696]
and point-in-plane. These work, but the equation is still stupid,
solving everything at once and not substituting trivial equations.
[git-p4: depot-paths = "//depot/solvespace/": change = 1677]
points are now entities like any others; so a line segment request
will generate three entities, the line segment and its endpoints. I
think that's cleaner.
When I do step and repeats (and imports, and other similar), I'll
need a consistent way to assign those entity ids. That assignment
must not change if the sketch is edited. I don't have a clean way
to do that; best thought right now is to keep a record of what maps
have been used previously, and not pick a new map as long as it's
possible to use one that was used previously.
This all means that more crap gets pushed in to the Entity
structure, so that they can keep track of what solver variables
define them. Still seems better, though. I'm closer to ready
to start solving.
