I began work on the Bezier sphere sweep last week.  The Bezier calculation macro
is already complete, and accommodates variable radii.  The hard part is to
integrate the Bezier calculation into my existing macros.

I will take a look at your file.  Please be aware that the Object Collection
requires the GNU Lesser General Public License (LGPL) 2.1, so if I end up
borrowing any of your code, you will need to consent to offering that license
before I can upload it.  The LGPL is just about the most generous license out
there, leaving you with little more than token ownership of your intellectual
property, so you'll want to read it very carefully before consenting to offer
it.
