[PATCH 0/2] MR1233: winex11.drv: Support _NET_WM_FULLSCREEN_MONITORS.

[Zhiyi Zhang (＠zhiyi)]

Support _NET_WM_FULLSCREEN_MONITORS for fullscreen windows spanning multiple monitors. This property
is used to hint window managers about which monitor a fullscreen window should cover. Window managers
make a fullscreen window spanning multiple monitors cover only one monitor when this property is missing.

Fix Project Cars 2/3 incorrect game window size when the triple-screen mode is on.
