	* xpdf/GOutputDev.h: add missing gdk include

	* xpdf/GOutputDev.cc (GOutputDev::drawLink): don't #if 0, just don't
	use it
	(GOutputDev::drawImage, GOutputDev::drawImageMask): use Michael's
	broken image handling code from gpdf 0.90.1 instead of my even
	more broken code

	* xpdf/gpdf-embeddable-view.cc (render_page): disable links here.
	(realize_mainbox): view == view_data now. Don't have to
	gtk_object_get_data anymore
	(real_redraw_view): ditto
	(redraw_view): ditto, make it static again
	(gpdf_embeddable_view_construct): connect redraw_view to
	pdf_changed signal, don't gtk_object_set_data "view_data"
	(view_switch_page, view_zoom_verb, view_activate)
	(button_press_event_cb, gesture_page_event_cb)
	(gesture_zoom_event_cb, key_press_event_cb, mainbox_realize): make
	them static again

	* xpdf/gpdf-embeddable.cc (class_init): add "pdf_changed" signal
	(load_pdf_from_stream): emit it, don't redraw_view explicitly

	* xpdf/gpdf-embeddable.h: add signal to class struct
