From a48c81dcdf569a3f634ac23e08d2491354de6a36 Mon Sep 17 00:00:00 2001
From: Peter Hutterer <peter.hutterer@who-t.net>
Date: Fri, 5 Dec 2008 16:24:57 +1000
Subject: [PATCH] Xi: add XATOM_FLOAT to server-defined properties.
This property is used to denote type float for input properties. Such
properties can be accessed easily through the XIPropToFloat() function.
Code originally written by Simon Thum.
