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

10611 database whereas it has not been created by XGetDefault
10612 (Bug#21974 in freedesktop.org Bugzilla). As a workaround, we
10613 don't destroy the database here in order to avoid the crash
10614 in the above situations for now, though that may cause memory
