This file contains a Mac PICT drawing that explains how
to make biosequence pictures with inverted, boxed text.
It isn't an easy process.  This was done with the Canvas version
3.5 application.  I seem to recall that version 3.0 or earlier
of Canvas doesn't work right with these instructions, but
I might be mistaken.  Also, I don't know if these apply to
MacDraw, ClarisDraw, etc.  I think they should, because the
process involves creating a Mac Quickdraw graphic that allso
maps into Postscript (for printer) in a way that preserves
inverse text -- it is this last point, that quickdraw and
postscript do inverse displays differently, that causes the
hassles here.
