Give up if glyph indices not supported. Use uniscribe obtained
ABC widths for individual metrics. Map glyph clusters back to
characters using fClusterStart flag. Return number of glyphs
produced, not chars processed.
* mouse.el (mouse-menu-non-singleton): Use it.
(mouse-major-mode-menu): Remove hack made unnecessary.
* keymap.c (Qkeymap_canonicalize): New var.
(Fmap_keymap_internal): New fun.
(describe_map): Use keymap-canonicalize.
(Fundo_boundary): Set them.
(syms_of_undo): Initialize them.
(record_point): Use them instead of last_point_position*.
(last_undo_buffer): Change type.
(Qdeseret, Qglagolitic, Qgothic, Qhanunoo, Qkharoshthi)
(Qlimbu, Qlinear_b, Qold_italic, Qold_persian, Qosmanya)
(Qphags_pa, Qphoenician, Qshavian, Qsyloti_nagri)
(Qtagalog, Qtagbanwa, Qtai_le, Qtifinagh, Qugaritic)
(Qphonetic): New symbols.
(syms_of_w32font): Initialize them.
(font_supported_scripts): Use them.
(w32font_list_family): List all charsets.
(w32font_text_extents, recompute_cached_metrics): Fix metric
calculations.
(w32_enumfont_pattern_entity): Make full_type a DWORD.
Give opentype fonts their own format.
(font_matches_spec): New arguments backend and logfont.
Handle :otf spec for uniscribe backend.
(add_font_entity_to_list): Match truetype fonts in uniscribe backend.
(fill_in_logfont): Use DEFAULT_CHARSET when charset not supplied.
(CATEGORY_MASK_UTF_16): Likewise.
(detect_coding_utf_16): Add heuristics to reject utf-16 for a
binary file.
(detect_coding): Add null-byte detection for a binary file.
(detect_coding_system): Likewise.
(command_loop_1): Avoid running the direct display versions of
forward-char and backward-char if shift-selection may occur.
Don't change the value of transient-mark-mode; this is now handled
by handle-shift-selection.
(read_key_sequence): Set Vthis_command_keys_shift_translated if
shift-translation takes place.
(Finteractive): Document new ^ spec.
(Fcall_interactively): Call handle-shift-selection if the ^ spec
is present.
* keyboard.c (Vthis_command_keys_shift_translated): New var.
(command_loop_1): Avoid running the direct display versions of
forward-char and backward-char if shift-selection may occur.
Don't change the value of transient-mark-mode; this is now handled
by handle-shift-selection.
(read_key_sequence): Set Vthis_command_keys_shift_translated if
shift-translation takes place.
* buffer.c (Vtransient_mark_mode): Move docstring to simple.el to
avoid clobbering by define-minor-mode.
* cmds.c (Fforward_char, Fbackward_char, Fforward_line)
(Fbeginning_of_line, Fend_of_line): Add ^ interactive spec.
* syntax.c (Fforward_word): Add ^ interactive spec.
* window.c (Fscroll_up, Fscroll_down, Fscroll_left)
(Fscroll_right): Add ^ interactive spec.
