if current start position is in a string or image.
(move_it_vertically_backward): Be sure to move out of strings and
images when moving it2 forward.
(move_it_by_lines): When moving forward, move to next buffer
position if we end up in a string or image. When moving backward,
count rows moved over when moving to start of current row in case
row starts in middle of a string or image. Also move further
backward if we end up in a string or image.
(try_cursor_movement): if overlay string spans multiple lines,
move backward to set cursor on start of an overlay string.
(cursor_row_p): Row is ok if cursor is at newline from string, but
string starts on this line (so we always position cursor at start
of string).
(x_use_underline_position_properties, last_mouse_press_frame)
(x_noop_count, Qvendor_specific_keysyms): Remove unused variables.
(syms_of_macterm, mac_initialize): Don't initialize them.
(waiting_for_input, initial_argv, initial_argc)
(Vcommand_line_args, Vx_no_window_manager, errno, window_scroll)
(set_frame_menubar, path_from_vol_dir_name): Remove externs.
(extra_keyboard_modifiers): Fix type in extern.
(x_window_to_frame, x_window_to_scroll_bar): Remove declarations.
(x_scroll_bar_report_motion): Add argument types to declaration.
(mac_compute_glyph_string_overhangs): Add declaration.
(disable_mouse_highlight): Remove unused variable.
[USE_TOOLKIT_SCROLL_BARS] (construct_scroll_bar_click)
(x_scroll_bar_handle_press, x_scroll_bar_handle_release)
(x_scroll_bar_handle_drag): Remove argument `timestamp'. All
callers changed.
[USE_TOOLKIT_SCROLL_BARS] (construct_scroll_bar_click): Don't set
timestamp.
[USE_CARBON_EVENTS] (mac_handle_mouse_event): Likewise.
(x_scroll_bar_create, XTset_vertical_scroll_bar): Show scroll bar
only when its width is less than the height.
(XTredeem_scroll_bar): Sync with xterm.c.
(font_name_table, font_name_table_size, font_name_count): Make
static.
(drag_and_drop_file_list): Remove variable. Previous use is now
local to function.
(do_ae_open_documents): Move DRAG_N_DROP event construction part
from XTread_socket.
(XTread_socket): Consolidate setting of event timestamp. Move
DRAG_N_DROP event construction part to do_ae_open_documents.
Support extra_keyboard_modifiers.
(ccl-encode-mac-cyrillic-font, ccl-encode-mac-symbol-font):
(ccl-encode-mac-dingbats-font): Remove check for ASCII. Change
charset-id boundary of dimension to ?\xef.
(mac-char-fontspec-list): New constant.
(fontset-add-mac-fonts): Use it. Accept non-string `base-family'
argument. Nil uses itself as family in font-spec. Previous
behavior for nil is now provided by non-nil non-string argument.
All callers changed. Add font-specs for Mac fonts to
"fontset-default" unless iso8859-1 fonts are installed.
[!MAC_OSX] (fchmod, fchown): New functions.
(mac_get_code_from_arg): Don't accept Lisp integer as argument.
Use SBYTES and EndianU32_BtoN.
(mac_get_object_from_code): Return 4 byte string even if argument
is 0. Use make_unibyte_string and EndianU32_NtoB.
(Fmac_get_file_creator, Fmac_get_file_type, Fmac_set_file_creator)
(Fmac_set_file_type): Fix documents and argument declarations.
Don't specify kFSCatInfoNodeFlags. Support Mac OS Classic.
