so always calculate heights even when pos-visible-in-window-p is
called with partially = t. Don't overshoot last_visible_y in move_it_to.
Return row height and row number in new rowh and vpos args.
(cursor_row_fully_visible_p): First line is always "fully visible".
(try_window): Don't clear matrix if vscrolled.
Return row height and row number for partially visible rows.
Modify return value to a 2 element list for fully visible rows
and 6 for partially visible row.
(window_scroll_pixel_based): Use pos_visible_p directly instead of
Fpos_visible_in_window_p. Fix auto vscrolling for partially visible lines.
Only vscroll backwards if already vscrolled forwards. Unconditionally
vscroll forwards if PT is first (and only) line. Set new window start
instead of scrolling at start/end of tall line.
(CHARS_MODIFF, BUF_CHARS_MODIFF): New macros.
* buffer.c (Fbuffer_chars_modified_tick): New function returning
value of BUF_CHARS_MODIFF.
(syms_of_buffer): Defsubr it.
(Fget_buffer_create): Initialize BUF_CHARS_MODIFF.
* insdel.c (modify_region): New argument preserve_chars_modiff.
Set CHARS_MODIFF to MODIFF provided preserve_chars_modiff is zero.
(insert_1_both, insert_from_string_1, insert_from_buffer_1)
(adjust_after_replace, adjust_after_replace_noundo)
(replace_range, replace_range_2, del_range_2): Reset CHARS_MODIFF.
* lisp.h (modify_region): Add fourth argument in extern.
* casefiddle.c (casify_region): Call modify_region with fourth
argument zero to assert that CHARS_MODIFF is updated.
* editfns.c (Fsubst_char_in_region, Ftranslate_region_internal)
(Ftranspose_regions): Likewise.
* textprop.c (Fadd_text_properties, Fset_text_properties)
(Fremove_text_properties, Fremove_list_of_text_properties):
Call modify_region with fourth argument 1 to avoid that
CHARS_MODIFF is updated.
with a hollow box cursor if image is larger than 32x32 (or the default
frame font if that is bigger). Replace any other cursor on images
with hollow box cursor, as redisplay doesn't support bar and hbar
cursors on images.
(x_iconify_frame, XLoadQueryFont, install_window_handler)
(mac_handle_command_event, init_command_handler, init_menu_bar):
Use OSStatus instead of OSErr.
(x_free_frame_resources) [TARGET_API_MAC_CARBON]: Don't use
FRAME_FILE_NAME.
(x_query_font): Apply 2006-08-04 change for xterm.c.
(Qhi_command): Rename from Qhicommand. All uses changed.
