Description Sven Gothel 2019-09-11 04:14:55 CEST 
NEWT X11Window didn't gather inset at window creation (properly)

X11Window.c's 'NewtWindows_getFrameExtends(..)'
retrieves the insets via XGetWindowProperty on _NET_FRAME_EXTENTS.

Right after window creation this method fails as the WM did not yet 
provide the information as the window has not yet been mapped.

Implementation needs to retry for a certain amount of time (250ms)
and maximum number of attempts (96 XEvent).

This issue surfaced while validating fix for Bug 1393,
testing TestDisplayLifecycle02NEWT also on X11.
