	* configure.in: Check for gtkhtml 0.9.99.1.

2001-07-02  Larry Ewing  <lewing@ximian.com>

	* mail-display.c (save_part): move the saving logic out of save_cb
	so that we can reuse it for the image saving code.
	(save_cb): call save_part.
	(save_url): new function to resolve an save an html url.
	(image_save_as): save function for images and.  Add it to the
	link_menu, and add MASK_URL and MASK_SRC to the structure so that
	we cans show the proper menus.
	(html_button_press_event): call get_src as well to find external
	urls references.  Add popup masking.
