text_width methods interface cleanup. -------------------- ChangeLog entries follow: -------------------- src/ChangeLog addition: 2011-12-28 Didier Verna <didier@xemacs.org> * console-impl.h (struct console_methods): Have the text_width methods expect a frame instead of a window pointer. * console-stream.c (stream_text_width): * redisplay-msw.c (mswindows_text_width): * redisplay-tty.c (tty_text_width): * redisplay-xlike-inc.c (XLIKE_text_width): Update accordingly. * redisplay-msw.c (mswindows_output_string): * redisplay-xlike-inc.c (XLIKE_output_string): * redisplay.c (redisplay_window_text_width_ichar_string): * redisplay.c (redisplay_text_width_string): Update the callers. This also fixes an uncertainty about always getting a window from a domain.
