Here's the patch for the Emacs 23.0.92 pretest (not the trunk HEAD).
* No configure support. The easiest way would be to compile it with
the GTK+ support that is already linked with cairo libs. Add
-DUSE_CAIRO to CFLAGS to activate the cairo code.
* With an experimental function (x-export-frame-image FRAME TYPE), you
can get the current FRAME screenshot as a unibyte string in TYPE
format. TYPE can be 'pdf, 'ps, 'png, or 'svg if the installed cairo
supports their formats.
* Currently, texts, rectangles (filling and stroking), and trapezoids
for reliefs are drawn using cairo by hooking the corresponding
drawing routine calls in xterm.c. They use X11 GC (with extension
data) for colors and clipping rectangles, but operations on them can
easily be ported to non-X11 (e.g., terminal-only) environments just
like the Carbon port.
* Images could also be drawn with cairo, but I didn't do that because
the image drawing in xterm.c depends on X-specific data structures.
As a result, you can't see any images in the exported screenshot as
of now.
* Stipples are ignored (both on screen and exported one).
* Exported png images seem to be incorrect in some cases. I suspect
it has something to do with cairo's cluttering the activated FT_Size
mentioned in ftcrfont.c, but I'm not sure.
