It has more support for transparency than I know what to do with.

Here's a snippet from the docs:

------------------------------------------------------------
void        cairo_set_source_rgb            (cairo_t *cr,
                                             double red,
                                             double green,
                                             double blue);
void        cairo_set_source_rgba           (cairo_t *cr,
                                             double red,
                                             double green,
                                             double blue,
                                             double alpha);
void        cairo_set_source                (cairo_t *cr,
                                             cairo_pattern_t *source);
void        cairo_set_source_surface        (cairo_t *cr,
                                             cairo_surface_t *surface,
                                             double x,
                                             double y);
cairo_pattern_t* cairo_get_source           (cairo_t *cr);

You can set the transparency of the colour, and, it appears, you can draw with
patterns and graphics.

Tony.

P.S. What version of libgnomeprint are you using now?  I read in the
libgnomeprint ChangeLog that transparency in PDF was fixed in a recent
release.
