Well, hard work is done. I got PNG images without using libgdgeda at
all. I have not compiled gschem with libgdgeda support, so maybe there
are some differences between the two ways, but this should be minor
tweaking now.

probably not, but I have not tested it. I made a copy of the toplevel
structure and I used a gdk pixmap when drawing the schematic to a
drawable, just before getting the pixbuf from it (I couldn't use a
gdk_drawing_area because it was not visible). Using this trick, I think
the window flashing when exporting to PNG is also removed.
