A file of type PICT is supposed to contain a 512-byte header area
(written as zeros unless a particular application wants to use it),
followed by the same data structure as a picture handle or PICT resource.
Either the old or new format picture should work (the new format will
appear blank in some old applications running very old System software).
The 512-byte header is "left over" from original (ie, 1984) MacPaint,
which stored user-customized patterns there.
