Subject: * xterm.c (XTread_socket): For ConfigureNotify, with x and y == 0,
X-Git-Tag: ttn-vms-21-2-B4~12950
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=0331883833db885c1de2708379bb7b351d213680;p=emacs.git

* xterm.c (XTread_socket): For ConfigureNotify, with x and y == 0,
and USE_MOTIF, call XTranslateCoordinates to get the real x and y.
This is to also handle x/y changes that occur because of a resize.
