By 2. Type1 indentification, do you mean dynamic type1 fonts declaration to
PDFlib? Like the stuff I'd for TrueType fonts file?
If that correct, I'll take this point 2.
BTW, I've already start... need to fix a segfault bug ;-)

Well, point 7 too! :-)

I'll vote against too.
We could wait PDFlib add support to this feature of PDF 1.4.
*Or*, we could hack something, like dithering the alpha channel into a binary
mask. Uh.

I'm taking point 2.
Okay, give me this point 1 too, bitmaps are fun and I've some experience since
bubblejet rasterization engine! ;-)

I (we) perfectly understand. As main contributor to this project, you're the
best PDF features aware member of the team: /me think it's better if you focus
on point 4 and 6, which, for one at least, don't really know how to implement.
On same topic, what about a v0.5 release on BeBits?
