I think I confused tkZinc and tkpath.  tkpath seems to use CoreGraphics, which
is 64-bit.

Your determination is admirable, I just think there are better areas to focus
your efforts.  Last I checked, tkpath is not really maintained.  We should
really be talking about pulling the GUI functions out of the Pd core, then
people can do things like write a GUI in C++, which will be dramatically
faster than anything written in Tcl/Tk.
