5f7d9a: Apply root window coordinate optimizations to crossing events as well

[Lars Ingebrigtsen]

This seems to lead to:

xterm.c: In function 'handle_one_xevent':
xterm.c:23931:13: warning: 'gen_help_time' may be used uninitialized in this 
function [-Wmaybe-uninitialized]
23931 |             xi_handle_interaction (dpyinfo, f,
      |             ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
23932 |                                    gen_help_device,
      |                                    ~~~~~~~~~~~~~~~~
23933 |                                    gen_help_time);
      |                                    ~~~~~~~~~~~~~~

(And the hours-long delays in gnu.org mailing lists seems to be
happening again.  Can somebody poke the people responsible?  It's really
annoying, and wastes time for everybody.)
