Subject: [PATCH] Steam patch

Steam, and steam windows (games), trigger a ConfigureNotify request every time the window
gets focus. More so, the configure event passed along from Steam tends to have the wrong
x and y coordinates which can make the window, if floating, jump around the screen.

This patch works around this age-old issue by ignoring the x and y co-ordinates for
ConfigureNotify requests relating to Steam windows.
