I think I hacked around this in a way not likely to break:  rather than
fixing the signature of PyAggImagePhoto,  I changed the call to
Tcl_CreateCommand to cast PyAggImagePhoto to the right thing.  I am
hopeful, but not certain, that this will work and saves us the trouble
of identifying at what version of Tcl/Tk this change occured.  I think
this hack is OK because the interface being changed looks so critical
that I'm surprised they even tweaked it.  I already committed it after
testing it on Linux (not really enough, I know).  I'll try Windows later
today.

Regards,
Todd
