[poppler] documentation?

[Ian Zimmerman]

Hi, I am trying to use poppler in a gtk 2.x program, but I can't find
any documentation and the details are overwhelming.  For instance,
looking at PopplerPage::poppler_page_render_to_pixbuf, what is the
meaning of src_x, src_y, src_width, src_height, and why are these
integers while poppler_page_get_size returns doubles?

Even a few comments in the headers files would help :-(

Am I overlooking something?
