* 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. svn path=/trunk/; revision=10707
