I should clarify: it says in IM-5, page 81:
  "There are several default color tables that are in the Macintosh II
ROMs.  There is one for each of the standard pixel depths.  The resource
ID for each table is the same as the depth.  For example, the default
color table used when you switch your system to 8 bits per pixel mode is
stored with resource ID = 8."

  This doesn't solve my problem, because since that was written, things
have changed.  There is now one default color table per depth for color
modes, and a *different* color table per depth for grayscale modes.  I need
to know how this works.  Is there a more complex resource ID numbering
scheme now?  Did 32-Bit QuickDraw patch something in an attempt to use the
correct table for whatever display was being "defaulted"?  Is there some
call that I'm not aware of that returns the correct table?  Etc.
