Subject: (mac_draw_bitmap): Handle 16 bits wide bitmaps directly.
X-Git-Tag: ttn-vms-21-2-B4~7639
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=dcd0c64591a4cd97cb5a23dea2bd1b12bacdbce7;p=emacs.git

(mac_draw_bitmap): Handle 16 bits wide bitmaps directly.
(x_draw_fringe_bitmap): Use enhanced mac_draw_bitmap, so we no longer
need to call mac_create_bitmap_from_bitmap_data and mac_free_bitmap.
