[vlc-devel] [PATCH 12/13] vout: resize display synchronously

[Rémi Denis-Courmont]

Like the splitter already does, this ensures that we do not queue a
large number of events via vout control upon drag-and-drop of the window.

This also prevents acknowledging the window resize before the resize is
actually handled (refs #20572).
