WM_DELETE_WINDOW does not send ClientMessage

[Roland Plüss]

Hi Lucien,

Depends what you call the same display. The window is created in the
render thread while event looping is done in the main thread. In both
places XOpenDisplay(getenv("DISPLAY")) is called. Is this not the same
display? If not how can I "attach" them together? It's a requirement
that the render thread creates the window while the main thread has to
handle the event loop (to my knowledge only this works).
