This commit contains a grab bag of minor changes not worth committing
individually:
* Replaced raw Latin-1 characters with octal escapes to avoid source-file
encoding issues
* Undefined some convenience macros after they've served their purpose
* Rewrote SEdge::From() to avoid confusing less-capable C++ compilers
* Have oops() print a newline at the end of its message
* Removed "static" keyword from the Bernstein() function definition, as it
has a non-static prototype in srf/surface.h
* Added casts (and changed a variable type) to quell warnings about integer
size and signedness
* Simplified an expression with our handy arraylen() macro
Later versions of libpng (1.5.x) have made the png_info structure opaque,
breaking direct access to its fields. Fortunately, the library also
provides getter routines, and these are available in the more-widely-
deployed 1.2.x series.
FLTK's Fl_Input widget, instantiated as {Graphics,Text}EditControl, returns
a 'const char *' string. In order to handle this properly, several of
SolveSpace's internal routines needed to gain a "const" qualifier on the
edit-control string argument.
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.
The compiler gets nervous when we (for example) pass in a size_t as an int
parameter, or assign an int to a char, or assign -1 to an unsigned type. By
adding appropriate casts, we inform the compiler that, yes, we know what
we're doing.
This change also upgrades a va_arg() type from char to int, as char is
always promoted to int when passed through '...'.
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.
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.

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.

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.

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.

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.

load it as a texture, and show it instead of a flat-color

translation of image, but the rotation is always aligned to the

to assemble Beziers into outer and inner loops, and find those
loops made up of entities with filled styles. The open paths are
maintained in a separate list, and we assemble as many closed paths
as possible even when open paths exist.
This changes many things. The coplanar check is now performed on
the Beziers, not the resulting polygon. The way that the polygon is
used to determine loop directions is also modified.
Also fix the mouse behavior when dragging a point: drop it when the
mouse is released, even if it is released outside the window, but
don't drop it if the pointer is dragged out of and then back into
our window.
Also special-case SSurface::ClosestPointTo() for planes, for speed.

I'll need that to do filled contour export for the 2d file formats.
Also add user interface to specify fill color.

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.

height and origin location.

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.

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.

steps in thisShell or thisMesh, and then let the Boolean proceed as
usual. If everything works, then this is equivalent. And it's less
code, and it makes stuff like stepping the step and repeat work.
Also begin to work on line/entity/constraint styles, but no real
work yet.
