The problem with bitmaps not being included in PostScript TEDIT documents
is (at least with Medley) is a bug in the SCALEDBITBLT system function (not
in my PostScript code).  I guess I should finish a bit of cleanup and release
the next version of POSTSCRIPTSTREAM (I shouldn't have called it PostScript,
since that is Adobe's trademark, so it has been renamed).  It does work with
bitmaps (even with scale factors other than just 1.0) in TEDIT documents.
(We use it here for our "AI News" internal newsletter.)  Also bitmap dumping
(e.g. screen snapshots) are **MUCH** faster.  The bitmap is written in a
compressed format and uncompressed in the printer.  (It takes half as long to
write the postscript output file on my 1186 as before, the file is about
one-fifth !! the size (for medium to large screen snapshots), communication is
faster to the printer (due to the smaller file), and even with the uncompressing
in the printer, it images the bitmap twice as fast in the printer.)

I'll send the latest version (on 360K floppy) to Arun Welch at ohio-state soon.
I'm willing to send a floppy to 1 central site in Europe for further
redistribution on the east side of the Atlantic, and also to 1 site
"down-under" for Australian redistribution.

I'm pleased that so many people are finding my package useful.  I have recieved
some suggestions for changes/improvements (some with code) for the package.  I
regret that I have little time for these enhancements, as "real work" must
always take precedence.  But I do plan to eventually try to integrate these all
together.
