Pffff... another tricky one...
-windowDidResize is actually also called when the window is not
resize by the user, leading to multiple event posting, and of
course the infamous call of ecore_main_loop_iterate() when it
was not paused at all, leading to messy events handling... the
most visible being the initial resizing of the window going rogue.
We now ensure with -windowWillStartLiveResize and -windowDidEndLiveResize
that we only send an event when the user requested it. Since the main
loop is paused at this point, calling ecore_main_loop_iterate()
