Log Message:
-----------
previously undocumented keith's modification because the change wasn't expected
to be user-visible, but it turns out it was (for pixel accurate grazing
selection), so credit us both for changing the spatial partition traversal
ordering. keith originally fixed a traversal 'bug' where it was walking cut
planes something like XYXYXYXYX (missing Z). he changed it to traverse
YZXYZXYZX, but that caused a different cell to get selected first and
differences were seen for overlapping objects. as a compromise, I modified the
change to instead traverse XYZXYZXYZ so the first two selections should be the
same as before (hopefully reducing differences, but they're still possible).
