put width before height consistently, fix a real bug found in the process -------------------- ChangeLog entries follow: -------------------- src/ChangeLog addition: 2010-02-20 Ben Wing <ben@xemacs.org> * EmacsFrame.c (EmacsFrameRecomputeCellSize): * faces.c (default_face_font_info): * faces.c (default_face_width_and_height): * faces.c (Fface_list): * faces.h: * frame-gtk.c (gtk_set_initial_frame_size): * frame-gtk.c (gtk_set_frame_size): * frame-gtk.c (gtk_recompute_cell_sizes): * frame.c: * frame.c (frame_conversion_internal_1): * frame.c (change_frame_size_1): * frame.c (change_frame_size): * glyphs-msw.c (mswindows_combo_box_instantiate): * glyphs-widget.c (widget_instantiate): * glyphs-widget.c (tree_view_query_geometry): * glyphs-widget.c (Fwidget_logical_to_character_width): * glyphs-widget.c (Fwidget_logical_to_character_height): * indent.c (vmotion_pixels): * redisplay-output.c (get_cursor_size_and_location): * redisplay-xlike-inc.c (XLIKE_output_eol_cursor): * redisplay-xlike-inc.c (XLIKE_flash): * redisplay.c (calculate_baseline): * redisplay.c (start_with_point_on_display_line): * redisplay.c (glyph_to_pixel_translation): * redisplay.c (pixel_to_glyph_translation): * window.c (margin_width_internal): * window.c (frame_size_valid_p): * window.c (frame_pixsize_valid_p): * window.c (check_frame_size): * window.c (set_window_pixsize): * window.c (window_pixel_height_to_char_height): * window.c (window_char_height_to_pixel_height): * window.c (window_displayed_height): * window.c (window_pixel_width_to_char_width): * window.c (window_char_width_to_pixel_width): * window.c (change_window_height): * window.c (window_scroll): * window.h: IMPORTANT: Aidan and Carbon Repo, please pay attention and fix appropriately! Rename: default_face_height_and_width -> default_face_width_and_height and reverse width/height arguments. Reverse width/height arguments to the following functions: -- default_face_font_info -- default_face_height_and_width (see above) -- check_frame_size -- frame_size_valid_p (made into a static function) Fix a redisplay bug where args to default_face_height_and_width were in the wrong order.
