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. */

/* These few functions implement Emacs as a normal Mac application
(almost): set up the heap and the Toolbox, handle necessary
system events plus a few simple menu events. They also set up
Emacs's access to functions defined in the rest of this file.
Emacs uses function hooks to perform all its terminal I/O. A
complete list of these functions appear in termhooks.h. For what
they do, read the comments there and see also w32term.c and
xterm.c. What's noticeably missing here is the event loop, which
is normally present in most Mac application. After performing the
necessary Mac initializations, main passes off control to
emacs_main (corresponding to main in emacs.c). Emacs_main calls
mac_read_socket (defined further below) to read input. This is
where WaitNextEvent is called to process Mac events. This is also
where check_alarm in sysdep.c is called to simulate alarm signals.
This makes the cursor jump back to its correct position after
