I have *absolutely* no use for the text, unless I'm completely replacing
the pdf with fields.

I don't need a reproduction of the PDF in livecode; I already have tools
for that.  I need the pdf itself.

AFAIK, it is impossible to take text from a pdf of unknown creation source
(or possibly pieced together by different editors) and maintain the exact
spacing.  Just for openers, I find font sizes that were apparently, say,
6.2, or line heights of 12.2, or that it three lines were generated with
the Mxyzptlk font that some employee happened to have on his computer and
he thought would be nice for that part.

A clerk or secretary printing the government version and my version on
acetate sheets to see if they line up to the pixel is an actual concern I
have to face (yes, there are folks with that much time on their hands).  In
the early 90s, I dropped this project (then in SuperCard 1.5) when the
clerk at the time told me that we would have to be exact *to the pixel* of
the new scanners they had coming in (which, to this date, have not
happened).

Except that I have a fairly tight size limits on uploaded files, and
arbitrarily large files will trample that fast on a 100 page pdf.

My software generates rules on how the contents of each field depends on
others.  I need to be laying my own fields in software, with the names I
give them (you don't think the government would remain all that consistent
between documents, do you? :)  besides, they don't define most of the names
I need anyway).

What I need is to be able to use an eps or a pdf as a display object, and
to export a pdf with that object.
