Finally tracked down coordinate scrambling bug.

Fixed the DNA problem.

Added UV-mesh cache so editing is fast, implemented NurbTrim. DNA is still buggy.

An entire day spent chasing mem management bugs :(

Removed platform-dependant timing code to fix build.

Progress commit: adding support for import+tessellate trim curves (mem mgt bugs).

Putting it all together: {BSpline,NURBS} values+derivates calculate & verify with Mathematica, smooth normals display properly.

NURBS surf eval + derivatives written (not verified), basis cache.

BSpline basis (derivs 0,1,2), BSpline surface (derivs 0,1) fix + verification in Mathematica

Eval debug rig

Added new eval code (computes first and second surface partials). Still buggy near multi-knots.

Fixed the memory leak bug, the bug that caused trimmed vertices to linger, and the bug that separated connected triangle faces produced with alt+c.

Added dumber+faster grid propagator, fixed displist crash bug for >~10x10 tessellation grids.

NURBS pushforward (U,V)->(x,y,z) works properly

Displist construction -- better commit it before I tear it up again

Promoted curve.c to cpp (changed extension, added casts), moved gridmesh into blenkernel/intern, the location of the old tessellation code, and moved the GLUT debug tool into the tests folder which seems like the appropriate place for it.

Timing code (TODO: REMOVE, it's platform-specific), reorganization of coords (now stored apart from verts) for compatibility with tess code.

BRep import base

Bugfix: inadvertant bool_SUB->bool_UNION fix for trimming verts that start in a grid cell but not in any of its polygons.

Boolean subtraction implemented and tested.
