Improve convergence of constraints involving parallel vectors, by using the initial numerical guess of whichever vector is already known to choose our projection planes. And add a mechanism to defer showing the text window or regenerating, in order to simplify dependencies on valid actives. Also yes/no/cancel when about to abandon an unsaved file, and a bugfix when rotating a rot/trans point. [git-p4: depot-paths = "//depot/solvespace/": change = 1772]

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. [git-p4: depot-paths = "//depot/solvespace/": change = 1925]

marching algorithm for surface intersection
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.

tangent intersections
Make surfaces of revolution with control points on the axis triangulate correctly; don't screw up generating them, and make sure that the ratpoly stuff doesn't blow up near the singularity. [git-p4: depot-paths = "//depot/solvespace/": change = 1953]

put back the meshes
Add a special constraint type for comments; no equations, just user-visible text. And make points hoverable/selectable even when GW.showPoints is false, and zoom to fit before regenerating on file open, because then we're at the right zoom level (and will use the right pwl tolerance).

Generate additional edges wherever a front- and back-facing triangle join. And add controls to show and hide the solid model edges (independently of the shaded mesh), and to suppress the shaded triangles from SVG/EPS output. [git-p4: depot-paths = "//depot/solvespace/": change = 1932]

incremental regen of entities?
Many changes: * Rewrite surface handles in curves, so that Booleans beyond the first don't screw up. * If an intersection curve is identical to an existing curve (as happens when faces are coincident), take the piecewise linearization of the existing curve; this stops us from screwing up when different shells are pwl'd at different chord tols. * Hook up the plane faces again. * Remove coincident (parallel or anti-parallel) edges from the coincident-face edge lists when doing Booleans; those may happen if two faces are coincident with ours. * Miscellaneous bugfixes. It doesn't seem to screw up very much now, although tangent edges (and insufficient pwl resolution) may still cause problems. [git-p4: depot-paths = "//depot/solvespace/": change = 1929]

IGES and STEP export
Add routines to remove T intersections from the mesh, which are 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. [git-p4: depot-paths = "//depot/solvespace/": change = 1821]
