	I've never tried it, but it would seem to me that in order for the
Palette Manager to know which colors to draw, they have to be valid entries
in the window's palette. To this end, I would pull the CLUT out of the PICT,
and do a CTab2Palette to get back a PaletteHandle, which you could then use
in a SetPalette call for the window.  Once the palette was in place, then
DrawPicture...If this doesn't work, then you may have to do the animation
yourself w/o the help of the Palette Manager.  It is not that difficult to
do color animation with just CLUTs.  I just finished a set of routines for
doing so (for some screen saver modules I am working on), so it can be done.
