From db81b0a1853fa8212bedda90429d180f0fe34297 Mon Sep 17 00:00:00 2001
From: Paul Gilbert
Date: Fri, 17 Jul 2009 05:10:24 +0000
Subject: Added an explicit break out of the event processing loop for mouse
 buttons and/or key-presses - this should allow stylus-based systems to
 properly process 'mouse down' events before the 'mouse up' is processed
