The notes I have on 32-bit QuickDraw include one on the enhancements
to the Palette Manager. In particular, it is possible to set up
the colour table in a source pixmap so that CopyBits will map the
source pixels onto animating entries in the palette of the target
window. All you have to do is set bit 14 in the ctFlags field,
and the value field in each element of the ctTable array becomes
a palette index, rather than a device CLUT index.

I assume this works in a PICT as well: all you have to do is find
and fiddle the appropriate bit, once you've created the PICT. You
could use either DeRez/Rez or PICT Detective to make the job a
little easier.

Disclaimer: I've never tried this. It just *looks* simple...
