Hi Steve,

Thanks so much for your contribution.

I've just committed these new functions. I also added support for
cairo_copy_page while I was at it.

I haven't tested these at all. Steve, presumably you've got a working
program that exercises these functions. Would you consider cooking up a
minimal PNG-based example that we could include in the pycairo
distribution?

PS. For future submissions, a patch file is much easier to work with
than just some code in an email message, (even if the amount of code is
very small). For example, I've attached a patch that I generated for the
change I just made. When working with CVS, this is as simple as grabbing
the output of "cvs diff -u" (modulo some annoyances when people without
cvs commit access want to generate a patch with new files). Outside of
cvs, it's simply a matter of putting an unmodified tree next to a
modified one and running something like "diff -urN" with the names of
both directories.
