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.
