From ee542b85590814ee25369babce1ad14feeb137af Mon Sep 17 00:00:00 2001 From: Chase Douglas Date: Tue, 1 May 2012 10:21:12 -0700 Subject: Report touch emulated buttons in XIQueryPointer for XI 2.1 and earlier XInput 2.1 and earlier clients do not know about touches. We must report touch emulated button presses for these clients. For later clients, we only report true pointer button presses.
