Here trimesh vs. trimesh is very unstable on OPCODE (with both single
and double precision); dropping a bunny in demo_moving_trimesh makes it
jitter until it falls to the ground. The same happens (but less
noticeable) with trimesh vs box and trimesh vs capsule (and maybe other
combinations too, which I didn't bother to test).

With GIMPACT there's almost no jitter; the only visual effect is the
trimesh/box/capsule slowly sliding away.


PS: someone forgot to update include/ode/Makefile.am when removed
odecpp_old.h.
