[PATCH 0/1] MR3241: winex11: Use gdi_display consistently for client_window requests.

[Rémi Bernon]

And synchronize with thread display when necessary.

The rationale is that client_window are created using the gdi_display,
and OpenGL/Vulkan using gdi_display it is probably safer that any X11
request for them is done on the gdi_display.

Then we need to properly synchronize the requests that involve client_window
and whole_window, such as reparenting requests, as whole_window is created,
and related requests make, using the thread display.
