This addresses a grab bag of compiler grievances relating to C++ syntax,
type, and scope, as observed on Linux with g++ and Solaris with Sun
WorkShop 6.
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.
as they are displayed on the drawing, and for many other places) a
user-configurable parameter.
Also reshuffle some options in the configuration screen, to put all
the stuff relating to exports together.

color picker.
And apply same rule to rewrite nearly-white colors (when exporting
with a file format typically viewed on a white background) for fill
color as for stroke color.
[git-p4: depot-paths = "//depot/solvespace/": change = 2176]
of that, where you can pick the hue and blackness, and then the
whiteness) color picker and some swatches.
This is used in three places now: the special colors in the config
screen, the background color, and the style colors.
[git-p4: depot-paths = "//depot/solvespace/": change = 2174]
in the text window. This means that I can move the conversion from
half-row and column to (x, y) into the platform-independent code,
and that I'll be ready to add my color picker.
[git-p4: depot-paths = "//depot/solvespace/": change = 2171]
circles, using a numerical method. And the user can specify a
radius, instead of letting us choose automatically, and specify
whether the original lines should be kept and made construction, or
deleted.
[git-p4: depot-paths = "//depot/solvespace/": change = 2146]
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.
[git-p4: depot-paths = "//depot/solvespace/": change = 2139]
buttons. This requires some tools to convert .png images to that,
and that I put the characters in a two-dimensional grid in the
texture (since one-dimensional strip gets wider than the hardware
supports).
[git-p4: depot-paths = "//depot/solvespace/": change = 2138]
default, let's do a "use perspective projection" item that's off by
default. Same meaning, but less confusion.
[git-p4: depot-paths = "//depot/solvespace/": change = 2132]
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.
[git-p4: depot-paths = "//depot/solvespace/": change = 2131]
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.
[git-p4: depot-paths = "//depot/solvespace/": change = 2130]
easy and useful. Also make the volume measurement use Message(),
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.
[git-p4: depot-paths = "//depot/solvespace/": change = 2121]
requires user interface to specify the depth, number of passes,
feed, and plunge feed, unfortunately.
[git-p4: depot-paths = "//depot/solvespace/": change = 2106]
rotation. Also clean up the handling of units, by putting the
conversion factors in only one place, and clean up the
expression-parsing but removing all the copies of the same error
message.
[git-p4: depot-paths = "//depot/solvespace/": change = 2093]
left-clicking always selects, and there's a special context menu
item to deselect. Also streamline the right-click behavior by
making that select the hovered item, and making all the context
menu items work on the selection.
[git-p4: depot-paths = "//depot/solvespace/": change = 2091]
selected entities, but cleared after dragging an unselected entity.
Marquee selection is select-only (not toggle), and "Select All"
replaces "Invert Selection". Left-click on nothing will clear the
selection.
Also add context menu entries for cut, copy, and paste.
[git-p4: depot-paths = "//depot/solvespace/": change = 2089]
does that, and adds a scale factor to that transformation (instead
of just mirroring, as before), but also:
* Replace the "import mirrored" mechanism with a scale factor,
which if negative corresponds to a reflection as well.
* Fix self-intersection checker to report a meaningful point
when edges are collinear.
* Don't blow an assertion on some types of invalid file;
instead provide a nice error message to the user.
* Clear the naked edges before each regen.
* Don't create zero-length line segments by snapping a line
segment's end to its beginning.
[git-p4: depot-paths = "//depot/solvespace/": change = 2086]
only in a workplane; but this means that plane sketches are
conveniently transformed from one plane to another.
Also tweak snap to grid to ignore unsnappable entities instead of
triggering an error, and to remove arbitrary limit on the number of
entities / comments that will be snapped.
[git-p4: depot-paths = "//depot/solvespace/": change = 2084]
because it can't be C2 continuous after splitting (since I'm
doing uniform splines only, and the parametrization changes). So
just knock everything down to cubic Beziers.
Also draw lines to indicate angle and origin when Ctrl+dragging to
rotate in plane of screen.
[git-p4: depot-paths = "//depot/solvespace/": change = 2075]
load it as a texture, and show it instead of a flat-color
background. Includes user interface to specify scale and
translation of image, but the rotation is always aligned to the
view.
[git-p4: depot-paths = "//depot/solvespace/": change = 2071]
under the just-deselected coincident point when I'm working on
batches, which really could have selected that underneath point.
And always pwl curves to at least two line segments (and likewise
retain at least one intermediate point when removing short edges),
to avoid confusion when holes end up square.
[git-p4: depot-paths = "//depot/solvespace/": change = 2070]
everything even partially within that rectangle gets selected when
I release.
Also make deselecting a point deselect all coincident points too;
otherwise there now exist ways to select both coincident points,
which meant that it was impossible to deselect the lower one.
And fix text window to show selection info even if just constraints
are selected, seems more consistent.
[git-p4: depot-paths = "//depot/solvespace/": change = 2066]
which can't be selected with the mouse and would otherwise have to
get deleted by selecting it in the text window.
[git-p4: depot-paths = "//depot/solvespace/": change = 2065]
one point to be dragged simultaneously. So now a dragged point
drags all the selected points and entities, and a dragged entity
drags its points (except for circles, which drag the radius).
This means that the number of forced points for the solver must now
be unlimited, and it is.
Also add commands to invert the selection within the active group,
and to select an edge chain starting from the current selection.
And redo the context menus a bit; still not great, but less
cluttered and more systematic.
[git-p4: depot-paths = "//depot/solvespace/": change = 2064]
contours go with which outer contour) out of exportstep.cpp, since
I'll need that to do filled contour export for the 2d file formats.
Also add user interface to specify fill color.
[git-p4: depot-paths = "//depot/solvespace/": change = 2057]
and parametric entities. Also consolidate the text screen functions
to change group options into a single function for everything.
[git-p4: depot-paths = "//depot/solvespace/": change = 2051]
point-coincident constraints and the entity- or group-generated
constraints. Also fix a bug where a dragged point was not released
when the mouse pointer left the window.
[git-p4: depot-paths = "//depot/solvespace/": change = 2045]
instead of tying that to whether the shaded model is shown. And
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
with ShellExecute seems to freeze a bit on startup.
[git-p4: depot-paths = "//depot/solvespace/": change = 2044]
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]
Constraint::COMMENTs), including line width and color, and text
height and origin location.
[git-p4: depot-paths = "//depot/solvespace/": change = 2033]
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.
[git-p4: depot-paths = "//depot/solvespace/": change = 2029]
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.
[git-p4: depot-paths = "//depot/solvespace/": change = 2028]
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.
[git-p4: depot-paths = "//depot/solvespace/": change = 2027]
(in my case, a SpaceNavigator). I can transform the view of the
part, or transform a part in an assembly.
Also fix up mouse wheel input, so that it works even if it comes in
chunks of less than 120 units.
[git-p4: depot-paths = "//depot/solvespace/": change = 2019]
a method that works on the piecewise linear segments, and then
refines any intersections that it finds by Newton's method. So now
I support cubics too, and circle-circle intersections, and the code
is much simpler.
[git-p4: depot-paths = "//depot/solvespace/": change = 2012]
feared. Though I don't have rational surfaces or curves going yet,
and I don't have the stuff to handle holes or multiple outer
contours in a single surface.
