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

9541 present in most Mac application. After performing the necessary
9542 Mac initializations, main passes off control to emacs_main
9543 (corresponding to main in emacs.c). Emacs_main calls XTread_socket
9544 (defined further below) to read input. This is where
9545 WaitNextEvent/ReceiveNextEvent is called to process Mac events. */

9699 - The table is meant for English language keyboards, and it will work
9700 for many others with the exception of key combinations like Fn-ö on
9701 a German keyboard, which is currently mapped to Fn-;.
9702 How to solve this without keeping separate tables for all keyboards
9703 around? KeyTranslate isn't of much help here, as it only takes a 16-bit
9704 value for keycode with the modifiers in he high byte, i.e. no room for the
9705 Fn modifier. That's why we need the table.
