+Subject: [PATCH] ANGLE: d3d11: Do not register windows message hooks for d3d11
+ windows
+
+These message hooks are used to handle ALT+ENTER to enter/exit fullscreen
+mode and PRINTSCREEN to take screenshots. Qt is implementing these
+functionalities itself so we do not have to register these hooks.
+
+If too many of these hooks are registered, callbacks are no longer called
+and Qt's message queue is no longer handling messages. By saving these
+hooks we can make sure that more Qt windows at the same time are possible
+without getting unresponsive due to too many hooks being registered.
