Subject: [PATCH xserver] present: Send a PresentConfigureNotify event for
|
|
destroyed windows

This enables fixing a deadlock case on the client side, where the client
|
|
ends up blocked waiting for a Present event that will never come because
|
|
the window was destroyed. The new PresentWindowDestroyed flag allows the
|
|
client to avoid blocking indefinitely.
