(EmacsFrameResize): Clean up coding style.
(EmacsFrameExpose): New function. Expose the frame here to
satisfy the toolkit when it calls the expose proc by hand.
* src/xterm.c (handle_one_xevent): Handle exposure through the
widget instead.
* etc/NEWS: Announce changes.
* src/w32fns.c (w32_set_inhibit_double_buffering): New function.

appropriate and set dirty flag.
* src/haikuterm.c (haiku_show_hourglass, haiku_hide_hourglass)

a tooltip is mapped.

(frame-hide-title-bar-when-maximized): New function (bug#31968).
Adapted from code by Jonathan Kyle Mitchell.

(xm_get_drag_window): Use that as the IO error handler when the
temporary display is open.
Change current-time and related functions back to using the
traditional list form. Also, add a new boolean variable
current-time-list that lets people try out (TICKS . HZ) form,
with the goal of smoothing the transition.
* src/timefns.c (CURRENT_TIME_LIST): Change default back to true.
(current-time-list): New boolean Lisp variable, which defaults to
CURRENT_TIME_LIST. All uses of CURRENT_TIME_LIST changed to
use current_time_list, and all documentation changed.

* src/font.c (Ffont_get, Ffont_put): Improve and clarify the doc
strings.

value is numeric, but still indicates that they are proportional,
to be proportional.
* lisp/textmodes/artist.el (artist-mode): Fix test for monospaced
fonts.
* src/xrdb.c (x_load_resources): Instead of specifying the Motif
defaults manually, let Motif set them itself. This makes

drop target is on during DND finish.
(x_connection_closed, x_delete_terminal): Handle display
disconnects during DND correctly.
This consolidates the test made in those two functions so as to make
sure they agree whether a window needs to be redisplayed.
At the same time, change this test so it uses the window's point
rather than the buffer's point when comparing to `w->last_point`.
* src/xdisp.c (needs_no_redisplay): New function, extracted from
`redisplay_window`.
(redisplay_window, prepare_menu_bars): Use it.
* src/window.c (window_point): New function, extracted from `Fwindow_point`.
(Fwindow_point): Use it.
* src/window.h (window_point): Declare it.
* src/sysdep.c (system_process_attributes) [CYGWIN]: Implement,
using the /proc filesystem. The code is identical to the
GNU/Linux code except for the 'ttname' attribute. (Bug#55153)
* etc/NEWS: Mention the change.

function directly.
(x_probe_xfixes_extension): Return directly based on dpyinfo.

`HAVE_XFIXES'.
