i can confirm that FPDF does very little more than just outputting
some text to a file.  this is as "PDF" as any other, it's just not
binary-encoded.  i think the only non-obvious thing to do is to
remember the file offsets where each page begins, so that at
file-closing time you can add the 'directory' part.

the second enhancement is not to repeat an embedded image, but to
create a 'resource' and use its definition on each usage.

(disclaimer, this is from hazy memory of reading several iterations of
the adobe specs, and the source of FPDF and Redland libs)
