Jonathan Westhues adc910185c Add plane-plane intersection as a special case (to generate the
trimmed line), and plane-line intersection. Terminate the Bezier
surface subdivision on a chord tolerance, and that seems okay now.
And print info about the graphics adapter in the text window, could
be useful.

Also have a cylinder-detection routine that works; should special
case those surfaces in closed form since they are common, but not
doing it yet.

Jonathan Westhues bc70089dd0 Add code to subdivide (with de Castljau's algorithm) a surface, and
use that for surface-line intersections. That has major problems
with the heuristic on when to stop and do Newton polishing.

There's also an issue with all the Newton stuff when surfaces join
tangent.

And update the wishlist to reflect current needs.

Jonathan Westhues 2023667311 Add Newton iterations to intersect a line with a surface at a
point, and to intersect three surfaces at a point. So now when we
split an edge, we can refine the split point to lie exactly on the
trim curve, so I can do certain Booleans on curved surfaces.

But surface-line intersection is globally broken, since I don't
correctly detect the number of intersections or provide a good
first guess. I maybe should test by bounding boxes and subdivision.

Jonathan Westhues 3da1e1d390 Compute surface intersections in a way that is closer to what I
will do for real; now handling the special cases of plane against a
surface of extrusion. Still need to fix up line-surface
intersection to work for curved things, but then some simple curved
cases should work (as well as plane-plane).

Jonathan Westhues 577cdf2255 More coincident fixing; test for edge-on-edge, fix some gross
stupidity.

Jonathan Westhues 90842131ff Make Boolean union work when the shells have coincident plane
faces. Still on planes only, no curved surface intersections.

Jonathan Westhues d0ab8270d9 Fix stupidity in Point2d::DistanceToLine, and classify line
segments in Boolean against the shell, not the intersection
polygon. (We just cast a ray, and use the surface-line intersection
function that already existed.) That's slow, but can be
accelerated later.

Jonathan Westhues 9ffe95ea65 More work on Booleans. This works only for planes, and only for
non-coincident faces. There's also a problem when I don't generate
the full intersection polygon of shell B against a given surface in
shell A; I need to modify the code to not require that.

Jonathan Westhues a754018a44 More poking at Booleans; generate the unsplit intersection curves
for planes against planes.
