This is the latest version of test cyl. Witch shows cylinder bug
I added a plane and moved cylinder and box to down on the plane instead of
Without the rotation ->cylinder stay on floor, with rotation the cylinder

Your talking about test_cyl, right?
If I add these 3 lines to reset_state() in test_cyl, test_cyl works just
fine for me.
(both single and double precision on linux, svn trunk)
Note that test_cyl does no cyl/plane isects, only cyl and box vs trimesh.
About cyl/plane isects: I think I'll redo the depth calculation, which may
fix the test_boxstack problem.
