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

I'll also revert e6a1956034c98204e30b0ca40330249d6f6f8155
in favour of this attempt
