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

9538 access to functions defined in the rest of this file. Emacs uses
9539 function hooks to perform all its terminal I/O. A complete list of
9540 these functions appear in termhooks.h. For what they do, read the
9541 comments there and see also w32term.c and xterm.c. What's
9542 noticeably missing here is the event loop, which is normally
9543 present in most Mac application. After performing the necessary
9544 Mac initializations, main passes off control to emacs_main
9545 (corresponding to main in emacs.c). Emacs_main calls XTread_socket
9546 (defined further below) to read input. This is where
9547 WaitNextEvent/ReceiveNextEvent is called to process Mac events. */

9698 The above table always translates to lower characters. We need to use

9701 - The table is meant for English language keyboards, and it will work
9702 for many others with the exception of key combinations like Fn-ö on
9703 a German keyboard, which is currently mapped to Fn-;.
9704 How to solve this without keeping separate tables for all keyboards
9705 around? KeyTranslate isn't of much help here, as it only takes a 16-bit
9706 value for keycode with the modifiers in he high byte, i.e. no room for the
9707 Fn modifier. That's why we need the table.
