The blitter functions that bobs use are integral to the bob handling
themselves.  They do not call the normally externally accessible
masked blitter ops as you have surmised.  The function qbliti() and/or
qbsblit() are called, the blitter is taken over by the bob function,
and its registers are directly manipulated.  At one time, while at
Amiga, I had looked into the work required to make those functions
externally accessible, but they are very tightly integrated into the
rest of the bob functions and it seemed pretty tough and R.J. was
pretty busy as it was trying to do Intuition (R.J. did the bob/vsprite/
animob system too, prior to doing the initial design and release of
Intuition).

I'd suggest you get the PD BlitLab stuff and see what you can discover
for your own application from that.  It is on a sorta recent FISH disk
and as I remember, it has some relatively-direct-access blitter
functions in source form that might be of help.  BlitLab is a
contribution of Tom Rokiki (see Tom - I spelled it right this time :-))
