That might be the case today, but as someone who has worked on the
Ghostscript code for many years now, I don't think you want to base
anything new on it if you can avoid it.  The CUPS raster driver pushes
Ghostscript to its limits, and we still have PDF problems in ESP
Ghostscript to fix... :(

Huh?  Xpdf provides nice C++ classes; these are not exposed in a
library right now, but doing so is trivial (Derek and I have talked
about this before...)

Let's find out if Derek is open to it before we talk doom-and-gloom.
I think if we can get him some sponsorship then it will make more
sense for him (and his business) to work with us...

See above.

I believe this is no longer accurate, but it should not be hard to
add since Xpdf tracks all of the PDF resources/state.

I believe that Splash supports arbitrary bit depths, and the current
usage of 8 bits is due to the X11/PPM limitations, not Xpdf's.

I don't think that is the issue, but rather that Derek is getting
money for doing X and not Y.
