merge most of rest of redisplay-x.c and redisplay-gtk.c into redisplay-xlike-inc.c -------------------- ChangeLog entries follow: -------------------- src/ChangeLog addition: 2010-01-18 Ben Wing <ben@xemacs.org> * redisplay-gtk.c: * redisplay-gtk.c (gtk_bevel_area): * redisplay-x.c: * redisplay-x.c (THIS_IS_X): * redisplay-xlike-inc.c: * redisplay-xlike-inc.c (XLIKE_text_width_single_run): * redisplay-xlike-inc.c (XLIKE_text_width): * redisplay-xlike-inc.c (XLIKE_output_display_block): * redisplay-xlike-inc.c (XLIKE_get_gc): * redisplay-xlike-inc.c (XLIKE_output_string): * redisplay-xlike-inc.c (XLIKE_OUTPUT_XLIKE_PIXMAP): * redisplay-xlike-inc.c (XLIKE_output_pixmap): * redisplay-xlike-inc.c (XLIKE_output_vertical_divider): * redisplay-xlike-inc.c (XLIKE_output_blank): * redisplay-xlike-inc.c (XLIKE_output_horizontal_line): * redisplay-xlike-inc.c (XLIKE_clear_region): * redisplay-xlike-inc.c (XLIKE_output_eol_cursor): * redisplay-xlike-inc.c (XLIKE_clear_frame_window): * redisplay-xlike-inc.c (XLIKE_clear_frame): * redisplay-xlike-inc.c (XLIKE_flash): * redisplay-xlike-inc.c (console_type_create_redisplay_XLIKE): Move lots more code into redisplay-xlike-inc.c. Use macros to isolate the code that differs among X vs. GTK, to reduce the need for ifdefs in the middle of the code. Now, redisplay-x.c and redisplay-gtk.c only contain a few functions whose implementation is completely different from one to the other, or which are not present at all in one of them. GTK code not currently tested, but it has bitrotted somewhat any. Doing this will help keep it less bitrotty. * depend: Regenerate.
