[PATCH v2 0/1] MR7552: winex11.drv: Resizing the window is allowed When the window is being restored...

[JiangYi Chen (＠meshine)]

winex11.drv: Resizing the window is allowed When the window is being restored from its maximized state.

When the window is restoring from the maximized state, its size should be adjustable.
 Some window managers may not correctly send the PropertyNotify event for the _NET_WM_STATE property
 When the window is maximized but its size is restricted to normal size by XSetWMNormalHints.
