/* X window system support for GNU Emacs
This file is part of the X window system support for GNU Emacs. It
contains subroutines comprising the redisplay interface, setting up
scroll bars and widgets, and handling input.
Some of what is explained below also applies to the other window
systems that Emacs supports, to varying degrees. YMMV.
INPUT
Emacs handles input by running pselect in a loop, which returns
whenever there is input available on the connection to the X
server. On some systems, Emacs also arranges for any new input on
that connection to send an asynchronous signal. Whenever pselect
returns, or such a signal is received and input is not blocked,
XTread_socket is called and translates X11 events read by Xlib into
struct input_events, which are then stored in the keyboard buffer,
to be processed and acted upon at some later time. The function
handle_one_xevent is responsible for handling core events after
they are filtered, and filtering X Input Extension events. It also
performs actions on some special events, such as updating the
dimensions of a frame after a ConfigureNotify is sent by the X
server to inform us that it changed.
Before such events are translated, an Emacs build with
internationalization enabled (the default since X11R6) will filter
events through an X Input Method (XIM) or GTK, which might decide
to intercept the event and send a different one in its place, for
reasons such as enabling the user to insert international
characters that aren't on his keyboard by typing a sequence of
characters which are. See the function x_filter_event and its
callers for more details.
Events that cause Emacs to quit are treated specially by the code
that stores them in the keyboard buffer and generally cause an
immediate interrupt. Such an interrupt can lead to a longjmp from
the code that stored the keyboard event, which isn't safe inside
XTread_socket. To avoid this problem, XTread_socket is provided a
special event buffer named hold_quit. When a quit event is
encountered, it is stored inside this special buffer, which will
cause the keyboard code that called XTread_socket to store it at a
later time when it is safe to do so.
handle_one_xevent will generally have to determine which frame an
event should be attributed to. This is not easy, because events
can come from multiple X windows, and a frame can also have
multiple windows. handle_one_xevent usually calls the function
x_any_window_to_frame, which searches for a frame by toplevel
window and widget windows. There are also some other functions for
searching by specific types of window, such as
x_top_window_to_frame (which only searches for frames by toplevel
window), and x_menubar_window_to_frame (which will only search
through frame menu bars).
INPUT FOCUS
Under X, the window where keyboard input is sent is not always
explicitly defined. When there is a focus window, it receives what
is referred to as "explicit focus", but when there is none, it
receives "implicit focus" whenever the pointer enters it, and loses
that focus when the pointer leaves. When the toplevel window of a
frame receives an explicit focus event (FocusIn or FocusOut), we
treat that frame as having the current input focus, but when there
is no focus window, we treat each frame as having the input focus
whenever the pointer enters it, and undo that treatment when the
pointer leaves it. See the callers of x_detect_focus_change for
more details.
REDISPLAY
The redisplay engine communicates with X through the "redisplay
interface", which is a structure containing pointers to functions
which output graphics to a frame.
Some of the functions included in the redisplay interface include
`x_clear_frame_area', which is called by the display engine when it
determines that a part of the display has to be cleared,
x_draw_window_cursor, which is called to perform the calculations
necessary to display the cursor glyph with a special "highlight"
(more on that later) and to set the input method spot location.
Most of the actual display is performed by the function
`x_draw_glyph_string', also included in the redisplay interface.
It takes a list of glyphs of the same type and face, computes the
correct graphics context for the string through the function
`x_set_glyph_string_gc', and draws whichever glyphs it might
contain, along with decorations such as the box face, underline and
overline. That list is referred to as a "glyph string".
GRAPHICS CONTEXTS
A graphics context ("GC") is an X server-side object which contains
drawing attributes such as fill style, stipple, and foreground and
background pixel values.
Usually, one graphics context is computed for each face when it is
about to be displayed for the first time, and this graphics context
is the one which is used for future X drawing operations in a glyph
string with that face. (See `prepare_face_for_display' in
xfaces.c).
However, when drawing glyph strings for special display elements
such as the cursor, or mouse sensitive text, different GCs may be
used. When displaying the cursor, for example, the frame's cursor
graphics context is used for the common case where the cursor is
drawn with the default font, and the colors of the string's face
are the same as the default face. In all other cases, a temporary
graphics context is created with the foreground and background
colors of the cursor face adjusted to ensure that the cursor can be
distinguished from its surroundings and that the text inside the
cursor stays visible.
Various graphics contexts are also calculated when the frame is
created by the function `x_make_gcs' in xfns.c, and are adjusted
whenever the foreground or background colors change. The "normal"
graphics context is used for operations performed without a face,
and always corresponds to the foreground and background colors of
the frame's default face, the "reverse" graphics context is used to
draw text in inverse video, and the cursor graphics context is used
to display the cursor in the most common case.
N.B. that some of the other window systems supported by use an
emulation of graphics contexts to hold the foreground and
background colors used in a glyph string, while the some others
ports compute those colors directly based on the colors of the
string's face and its highlight, but only on X are graphics
contexts a data structure inherent to the window system.
COLOR ALLOCATION
In (and only in) X, pixel values for colors are not guaranteed to
correspond to their individual components. The rules for
converting colors into pixel values are defined by the visual class
of each display opened by Emacs. When a display is opened, a
suitable visual is obtained from the X server, and a colormap is
created based on that visual, which is then used for each frame
created.
The colormap is then used by the X server to convert pixel values
from a frame created by Emacs into actual colors which are output
onto the physical display.
When the visual class is TrueColor, the colormap will be indexed
based on the red, green, and blue (RGB) components of the pixel
values, and the colormap will be statically allocated so as to
contain linear ramps for each component. As such, most of the
color allocation described below is bypassed, and the pixel values
are computed directly from the color.
Otherwise, each time Emacs wants a pixel value that corresponds to
a color, Emacs has to ask the X server to obtain the pixel value
that corresponds to a "color cell" containing the color (or a close
approximation) from the colormap. Exactly how this is accomplished
further depends on the visual class, since some visuals have
immutable colormaps which contain color cells with pre-defined
values, while others have colormaps where the color cells are
dynamically allocated by individual X clients.
With visuals that have a visual class of StaticColor and StaticGray
(where the former is the case), the X server is asked to procure
the pixel value of a color cell that contains the closest
approximation of the color which Emacs wants. On the other hand,
when the visual class is DirectColor, PseudoColor, or GrayScale,
where color cells are dynamically allocated by clients, Emacs asks
the X server to allocate a color cell containing the desired color,
and uses its pixel value.
(If the color already exists, the X server returns an existing color
cell, but increases its reference count, so it still has to be
freed afterwards.)
Otherwise, if no color could be allocated (due to the colormap
being full), Emacs looks for a color cell inside the colormap
closest to the desired color, and uses its pixel value instead.
Since the capacity of a colormap is finite, X clients have to take
special precautions in order to not allocate too many color cells
that are never used. Emacs allocates its color cells when a face
is being realized or when a frame changes its foreground and
background colors, and releases them alongside the face or frame.
See calls to `unload_color' and `load_color' in xterm.c, xfaces.c
and xfns.c for more details.
The driving logic behind color allocation is in
`x_alloc_nearest_color_1', while the optimization for TrueColor
visuals is in `x_make_truecolor_pixel'. Also see `x_query_colors`,
which is used to determine the color values for given pixel
values.
In other window systems supported by Emacs, color allocation is
handled by the window system itself, to whom Emacs simply passes 24
(or 32-bit) RGB values.
OPTIONAL FEATURES
While X servers and client libraries tend to come with many
extensions to the core X11R6 protocol, dependencies on anything
other than the core X11R6 protocol and Xlib should be optional at
both compile-time and runtime. Emacs should also not crash
regardless of what combination of X server and client-side features
are present. For example, if you are developing a feature that
will need Xfixes, then add a test in configure.ac for the library
at compile-time which defines `HAVE_XFIXES', like this:
### Use Xfixes (-lXfixes) if available
HAVE_XFIXES=no
if test "${HAVE_X11}" = "yes"; then
XFIXES_REQUIRED=4.0.0
XFIXES_MODULES="xfixes >= $XFIXES_REQUIRED"
EMACS_CHECK_MODULES([XFIXES], [$XFIXES_MODULES])
if test $HAVE_XFIXES = no; then
# Test old way in case pkg-config doesn't have it (older machines).
AC_CHECK_HEADER([X11/extensions/Xfixes.h],
[AC_CHECK_LIB([Xfixes], [XFixesHideCursor], [HAVE_XFIXES=yes])])
if test $HAVE_XFIXES = yes; then
XFIXES_LIBS=-lXfixes
fi
fi
if test $HAVE_XFIXES = yes; then
AC_DEFINE([HAVE_XFIXES], [1],
[Define to 1 if you have the Xfixes extension.])
fi
fi
AC_SUBST([XFIXES_CFLAGS])
AC_SUBST([XFIXES_LIBS])
Then, make sure to adjust CFLAGS and LIBES in src/Makefile.in and
add the new XFIXES_CFLAGS and XFIXES_LIBS variables to
msdos/sed1v2.inp. (The latter has to be adjusted for any new
variables that are included in CFLAGS and LIBES even if the
libraries are not used by the MS-DOS port.)
Finally, add some fields in `struct x_display_info' which specify
the major and minor versions of the extension, and whether or not to
support them. They (and their accessors) should be protected by the
`HAVE_XFIXES' preprocessor conditional. Then, these fields should
be set in `x_term_init', and all Xfixes calls must be protected by
not only the preprocessor conditional, but also by checks against
those variables.
X TOOLKIT SUPPORT
Emacs supports being built with many different toolkits (and also no
toolkit at all), which provide decorations such as menu bars and
scroll bars, along with handy features like file panels, dialog
boxes, font panels, and popup menus. Those configurations can
roughly be classified as belonging to one of three categories:
- Using no toolkit at all.
- Using the X Toolkit Intrinsics (Xt).
- Using GTK.
The no toolkit configuration is the simplest: no toolkit widgets are
used, Emacs uses its own implementation of scroll bars, and the
XMenu library that came with X11R2 and earlier versions of X is used
for popup menus. There is also no complicated window structure to
speak of.
The Xt configurations come in either the Lucid or Motif flavors.
The former utilizes Emacs's own Xt-based Lucid widget library for
menus, and Xaw (or derivatives such as neXTaw and Xaw3d) for dialog
boxes and, optionally, scroll bars. It does not support file
panels. The latter uses either Motif or LessTif for menu bars,
popup menus, dialogs and file panels.
The GTK configurations come in the GTK+ 2 or GTK 3 configurations,
where the toolkit provides all the aforementioned decorations and
features. They work mostly the same, though GTK 3 has various small
annoyances that complicate maintenance.
All of those configurations have various special technicalities
about event handling and the layout of windows inside a frame that
must be kept in mind when writing X code which is run on all of
them.
The no toolkit configuration has no noteworthy aspects about the
layout of windows inside a frame, since each frame has only one
associated window aside from scroll bars. However, in the Xt
configurations, every widget is a separate window, and there are
quite a few widgets. The "outer widget", a widget of class
ApplicationShell, is the top-level window of a frame. Its window is
accessed via the macro `FRAME_OUTER_WINDOW'. The "edit widget", a
widget class of EmacsFrame, is a child of the outer widget that
controls the size of a frame as known to Emacs, and is the widget
that Emacs draws to during display operations. The "menu bar
widget" is the widget holding the menu bar.
Special care must be taken when performing operations on a frame.
Properties that are used by the window manager, for example, must be
set on the outer widget. Drawing, on the other hand, must be done
to the edit widget, and button press events on the menu bar widget
must be redirected and not sent to Xt until the Lisp code is run to
update the menu bar.
The EmacsFrame widget is specific to Emacs and is implemented in
widget.c. See that file for more details.
In the GTK configurations, GTK widgets do not necessarily correspond
to X windows, since the toolkit might decide to keep only a
client-side record of the widgets for performance reasons.
Because the GtkFixed widget that holds the "edit area" might not
correspond to an X window, drawing operations may be directly
performed on the outer window, with special care taken to not
overwrite the surrounding GTK widgets. This also means that the
only important window for most purposes is the outer window, which
on GTK builds can usually be accessed using the macro
`FRAME_X_WINDOW'.
How `handle_one_xevent' is called also depends on the configuration.
Without a toolkit, Emacs performs all event processing by itself,
running XPending and XNextEvent in a loop whenever there is input,
passing the event to `handle_one_xevent'.
When using Xt, the same is performed, but `handle_one_xevent' may
also decide to call XtDispatchEvent on an event after Emacs finishes
processing it.
When using GTK, however, `handle_one_xevent' is called from an event
filter installed on the GTK event loop. Unless the event filter
elects to drop the event, it will be passed to GTK right after
leaving the event filter.
Fortunately, `handle_one_xevent' is provided a `*finish' parameter
that abstracts away all these details. If it is `X_EVENT_DROP',
then the event will not be dispatched to Xt or utilized by GTK.
Code inside `handle_one_xevent' should thus avoid making assumptions
about the event dispatch mechanism and use that parameter
instead.
FRAME RESIZING
In the following explanations "frame size" refers to the "native
size" of a frame as reported by the (frame.h) macros
FRAME_PIXEL_WIDTH and FRAME_PIXEL_HEIGHT. These specify the size of
a frame as the values passed to/received from a toolkit and the
window manager. The "text size" Emacs Lisp code uses in functions
like 'set-frame-size' or sees in the ‘width’ and 'height' frame
parameters is only loosely related to the native size. The
necessary translations are provided by the macros
FRAME_TEXT_TO_PIXEL_WIDTH and FRAME_TEXT_TO_PIXEL_HEIGHT as well as
FRAME_PIXEL_TO_TEXT_WIDTH and FRAME_PIXEL_TO_TEXT_HEIGHT (in
frame.h).
Lisp functions may ask for resizing a frame either explicitly, using
one of the interfaces provided for that purpose like, for example,
'set-frame-size' or changing the 'height' or 'width' parameter of
that frame, or implicitly, for example, by turning off/on or
changing the width of fringes or scroll bars for that frame. Any
such request passes through the routine 'adjust_frame_size' (in
frame.c) which decides, among others, whether the native frame size
would really change and whether it is allowed to change it at that
moment. Only if 'adjust_frame_size' decides that the corresponding
terminal's 'set_window_size_hook' may be run, it will dispatch
execution to the appropriate function which, for X builds, is
'x_set_window_size' in this file.
For GTK builds, 'x_set_window_size' calls 'xg_frame_set_char_size'
in gtkutil.c if the frame has an edit widget and
'x_set_window_size_1' in this file otherwise. For non-GTK builds,
'x_set_window_size' always calls 'x_set_window_size_1' directly.
'xg_frame_set_char_size' calls the GTK function 'gtk_window_resize'
for the frame's outer widget; x_set_window_size_1 calls the Xlib
function 'XResizeWindow' instead. In either case, if Emacs thinks
that the frame is visible, it will wait for a ConfigureNotify event
(see below) to occur within a timeout of 'x-wait-for-event-timeout'
(the default is 0.1 seconds). If Emacs thinks that the frame is not
visible, it calls 'adjust_frame_size' to run 'resize_frame_windows'
(see below) and hopes for the best.
Note that if Emacs receives a ConfigureEvent in response to an
earlier resize request, the sizes specified by that event are not
necessarily the sizes Emacs requested. Window manager and toolkit
may override any of the requested sizes for their own reasons.
On X, size notifications are received as ConfigureNotify events.
The expected reaction to such an event on the Emacs side is to
resize all Emacs windows that are on the frame referred to by the
event. Since resizing Emacs windows and redisplaying their buffers
is a costly operation, Emacs may collapse several subsequent
ConfigureNotify events into one to avoid that Emacs falls behind in
user interactions like resizing a frame by dragging one of its
borders with the mouse.
Each ConfigureEvent event specifies a window, a width and a height.
The event loop uses 'x_top_window_to_frame' to associate the window
with its frame. Once the frame has been identified, on GTK the
event is dispatched to 'xg_frame_resized'. On Motif/Lucid
'x_window' has installed 'EmacsFrameResize' as the routine that
handles resize events. In either case, these routines end up
calling the function 'change_frame_size' in dispnew.c. On
non-toolkit builds the effect is to call 'change_frame_size'
directly from the event loop. In either case, the value true is
passed as the DELAY argument.
'change_frame_size' is the central function to decide whether it is
safe to process a resize request immediately or it has to be delayed
(usually because its DELAY argument is true). Since resizing a
frame's windows may run arbitrary Lisp code, Emacs cannot generally
process resize requests during redisplay and therefore has to queue
them. If processing the event must be delayed, the new sizes (that
is, the ones requested by the ConfigureEvent) are stored in the
new_width and new_height slots of the respective frame structure,
possibly replacing ones that have been stored there upon the receipt
of a preceding ConfigureEvent.
Delayed size changes are applied eventually upon calls of the
function 'do_pending_window_change' (in dispnew.c) which is called
by the redisplay code at suitable spots where it's safe to change
sizes. 'do_pending_window_change' calls 'change_frame_size' with
its DELAY argument false in the hope that it is now safe to call the
function 'resize_frame_windows' (in window.c) which is in charge of
adjusting the sizes of all Emacs windows on the frame accordingly.
Note that if 'resize_frame_windows' decides that the windows of a
frame do not fit into the constraints set up by the new frame sizes,
it will resize the windows to some minimum sizes with the effect
that parts of the frame at the right and bottom will appear clipped
off.
In addition to explicitly passing width and height values in
functions like 'gtk_window_resize' or 'XResizeWindow', Emacs also
sets window manager size hints - a more implicit form of asking for
the size Emacs would like its frames to assume. Some of these hints
only restate the size and the position explicitly requested for a
frame. Another hint specifies the increments in which the window
manager should resize a frame to - either set to the default
character size of a frame or to one pixel for a non-nil value of
'frame-resize-pixelwise'. See the function 'x_wm_set_size_hint' -
in gtkutil.c for GTK and in this file for other builds - for the
details.
We have not discussed here a number of special issues like, for
example, how to handle size requests and notifications for maximized
and fullscreen frames or how to resize child frames. Some of these
require special treatment depending on the desktop or window manager
used.
One thing that might come handy when investigating problems wrt
resizing frames is the variable 'frame-size-history'. Setting this
to a non-nil value, will cause Emacs to start recording frame size
adjustments, usually specified by the function that asked for an
adjustment, a sizes part that records the old and new values of the
frame's width and height and maybe some additional information. The
internal function `frame--size-history' can then be used to display
the value of this variable in a more readable form.
FRAME RESIZE SYNCHRONIZATION
The X window system operates asynchronously. That is to say, the
window manager and X server might think a window has been resized
before Emacs has a chance to process the ConfigureNotify event that
was sent.
When a compositing manager is present, and the X server and Emacs
both support the X synchronization extension, the semi-standard
frame synchronization protocol can be used to notify the compositing
manager of when Emacs has actually finished redisplaying the
contents of a frame after a resize. The compositing manager will
customarily then postpone displaying the contents of the frame until
the redisplay is complete.
Emacs announces support for this protocol by creating an X
server-side counter object, and setting it as the
`_NET_WM_SYNC_REQUEST_COUNTER' property of the frame's top-level
window. The window manager then initiates the synchronized resize
process by sending Emacs a ClientMessage event before the
ConfigureNotify event where:
type = ClientMessage
window = the respective client window
message_type = WM_PROTOCOLS
format = 32
data.l[0] = _NET_WM_SYNC_REQUEST
data.l[1] = timestamp
data.l[2] = low 32 bits of a provided frame counter value
data.l[3] = high 32 bits of a provided frame counter value
data.l[4] = 1 if the extended frame counter should be updated,
otherwise 0
Upon receiving such an event, Emacs constructs and saves a counter
value from the provided low and high 32 bits. Then, when the
display engine tells us that a frame has been completely updated
(presumably because of a redisplay caused by a ConfigureNotify
event), we set the counter to the saved value, telling the
compositing manager that the contents of the window now accurately
reflect the new size. The compositing manager will then display the
contents of the window, and the window manager might also postpone
updating the window decorations until this moment.
DRAG AND DROP
Drag and drop in Emacs is implemented in two ways, depending on
which side initiated the drag-and-drop operation. When another X
client initiates a drag, and the user drops something on Emacs, a
`drag-n-drop-event' is sent with the contents of the ClientMessage,
and further processing (i.e. retrieving selection contents and
replying to the initiating client) is performed from Lisp inside
`x-dnd.el'.
However, dragging contents from Emacs is implemented almost entirely
in C. X Windows has several competing drag-and-drop protocols, of
which Emacs supports two on the C level: the XDND protocol (see
https://freedesktop.org/wiki/Specifications/XDND) and the Motif drag
and drop protocols. These protocols are based on the initiator
owning a special selection, specifying an action the recipient
should perform, grabbing the mouse, and sending various different
client messages to the toplevel window underneath the mouse as it
moves, or when buttons are released.
The Lisp interface to drag-and-drop is synchronous, and involves
running a nested event loop with some global state until the drag
finishes. When the mouse moves, Emacs looks up the toplevel window
underneath the pointer (the target window) either using a cache
provided by window managers that support the
_NET_WM_CLIENT_LIST_STACKING root window property, or by calling
XTranslateCoordinates in a loop until a toplevel window is found,
and sends various entry, exit, or motion events to the window
containing a list of targets the special selection can be converted
to, and the chosen action that the recipient should perform. The
recipient can then send messages in reply detailing the action it
has actually chosen to perform. Finally, when the mouse buttons are
released over the recipient window, Emacs sends a "drop" message to
the target window, waits for a reply, and returns the action
selected by the recipient to the Lisp code that initiated the
drag-and-drop operation.
When a drop happens on a window not supporting any protocol
implemented on the C level, the function inside
`x-dnd-unsupported-drop-function' is called with some parameters of
the drop. If it returns non-nil, then Emacs tries to simulate a
drop happening with the primary selection and synthetic button
events (see `x_dnd_do_unsupported_drop'). That function implements
the OffiX drag-and-drop protocol by default. See
`x-dnd-handle-unsupported-drop' in `x-dnd.el' for more details. */

/* From the XDND protocol specification:
Dropping on windows that do not support XDND
Since middle clicking is the universal shortcut for pasting
in X, one can drop data into a window that does not support
XDND by:
1. After the mouse has been released to trigger the drop,
obtain ownership of XA_PRIMARY.
2. Send a ButtonPress event and then a ButtonRelease event to
the deepest subwindow containing the mouse to simulate a
middle click. The times for these events should be the time
of the actual button release +1 and +2, respectively. These
values will not be used by anybody else, so one can
unambiguously recognize the resulting `XConvertSelection'
request.
3. If a request for XA_PRIMARY arrives bearing the timestamp
of either the ButtonPress or the ButtonRelease event, treat
it as a request for XdndSelection. Note that you must use
the X data types instead of the MIME types in this case.
(e.g. XA_STRING instead of text/plain). */

Keeping track of scroll valuators is required in order to support
scroll wheels that report information in a fashion more detailed
than a single turn of a "step" in the wheel.
When the input extension is being utilized, the states of the mouse
wheels on each axis are stored as absolute values inside
"valuators" attached to each mouse device. To obtain the delta of
the scroll wheel from a motion event (which is used to report that
some valuator has changed), it is necessary to iterate over every
valuator that changed, and compare its previous value to the
current value of the valuator.
Each individual valuator also has an "interval", which is the
amount you must divide that delta by in order to obtain a delta in
the terms of scroll units.
This delta however is still intermediate, to make driver
implementations easier. The XInput developers recommend (and most
programs use) the following algorithm to convert from scroll unit
deltas to pixel deltas by which the display must actually be
scrolled:

ridiculously large value, and this way a more reasonable timestamp
can be obtained upon the next event.
Alternatively, the server time could've overflowed.
SET_PROPERTY specifies whether or not to change the user time
property for the active frame. The important thing is to not set
the last user time upon leave events; on Metacity and GNOME Shell,
mapping a new frame on top of the old frame potentially causes
crossing events to be sent to the old frame if it contains the
pointer, as the new frame will initially stack above the old frame.
If _NET_WM_USER_TIME is changed at that point, then GNOME may get
notified about the user time change on the old frame before it
tries to focus the new frame, which will make it consider the new
frame (whose user time property will not have been updated at that
point, due to not being focused) as having been mapped
out-of-order, and lower the new frame, which is typically not what
users want. */

/* Mouse clicks and mouse movement. Rah.
Formerly, we used PointerMotionHintMask (in standard_event_mask)
so that we would have to call XQueryPointer after each MotionNotify
event to ask for another such event. However, this made mouse tracking
slow, and there was a bug that made it eventually stop.
Simply asking for MotionNotify all the time seems to work better.
In order to avoid asking for motion events and then throwing most
of them away or busy-polling the server for mouse positions, we ask
the server for pointer motion hints. This means that we get only
one event per group of mouse movements. "Groups" are delimited by
other kinds of events (focus changes and button clicks, for
example), or by XQueryPointer calls; when one of these happens, we
get another MotionNotify event the next time the mouse moves. This
is at least as efficient as getting motion events when mouse
tracking is on, and I suspect only negligibly worse when tracking
is off. */

After calling this function, X protocol errors generated on DPY no
longer cause Emacs to exit; instead, they are recorded in an error
handler pushed onto the stack `x_error_message'.
Calling x_check_errors signals an Emacs error if an X error has
occurred since the last call to x_catch_errors or x_check_errors.
Calling x_uncatch_errors resumes the normal error handling,
skipping an XSync if the last request made is known to have been
processed. Calling x_uncatch_errors_after_check is similar, but
always skips an XSync to the server, and should be used only
immediately after x_had_errors_p or x_check_errors, or when it is
known that no requests have been made since the last x_catch_errors
call for DPY.
