I did not use this syntax in thumbpdf, but the first
form, because of:

* Space: pdfTeX inserts a lot of spaces, that are not needed,
  writing the stream directly can be done more compact.
* Compression: compression factor can be set independent
  for the thumbnails.
* Speed: pdfTeX does not need to compress the object stream.
