Resolves: tdf#91393 autotext (etc) not fully drawn

the paint timer is activating after we ask gtk to
size the window but before we/gtk get the ConfigureNotify
that updates gtk knowledge of the size. So the gtk drawing
calls are clipped to the previous ConfigureNotify size.

So, lets try postponing paints if we have set a size but
not received a configure notify yet

another stab at tdf#91393

block paints only if the new requested size is larger than the original and
unblock on explicit expose events as well as configure ones
