[I'm copying the cairo list as well, (yes, evil cross-posting). Feel

For the cairo list: This is a response I got on the inkscape-devel
list when asking for some testing of "export to PDF" in inkscape with
the recent cairo 1.5.2 snapshot.

Ooh. That looks like a pretty nice test. I'll definitely have to play
with that some.

Yes, this sounds expected as we've found bugs in evince/poppler
exposed by the recent improvements to cairo's PDF output. See this
Poppler does not yet handle everything in the cairo test suite
as well as the other bugs it depends on. Specifically, this one is
probably the one you're hitting:
Poppler doesn't correctly handle gradients with transparency

That's good. That puts the bugs in poppler's court, not cairo's.

And this is where things get interesting. I think cairo-pdf should
support all of that. So either something is still in missing in cairo
that I'm not aware of, or something could be improved in inkscape with
regards to the way it is using cairo, (or some combination of course).
If anyone that could take a closer look and give more details about
any of these issues, that would be greatly appreciated.
Thanks for the quick feedback!
