What you've got there is a 32-bit PICT. OpCode $9A means DirectBitsRect,
provided that you have 32-bit QuickDraw running. Otherwise, as you've
noted, regular Color QuickDraw sees an unassigned OpCode with a data length
of zero followed by an end-of-picture code. This was done intentionally. A
pixelType of 16 means RGBDirect under 32-bit QD and a packType of 4 denotes
a particular type of run-length encoding that's too involved to go into
here, but it's the default packType used when the pixelSize is 32.
What you need is documentation for 32-bit QuickDraw which, I believe, is
available from APDA.
