Start using the new wl_fixed_t type properly

The mouse and touch coordinates cannot just be treated as integers
anymore, they need to be converted from/to double using the helper
functions. Some necessary QPoint -> QPointF changes have also been
made.

For the Qt-specific touch extension we will not switch to wl_fixed_t
though. This is because the precision is unfortunately quite small
(factor of 256 vs. 10000).

Send expose from qwindow-compositor

Otherwise apps that (correctly) only start rendering on QEvent::Expose
will not render at all due to not receiving the event.

Turns out calling sendOnScreenVisibilityChange() is not that simple:
It does nothing until the extendedsurface instance is created and that
happens only after a roundtrip to the client. Therefore the compositor
listens to a new signal in WaylandSurface that indicates when the
extendedsurface-related functions become functional.
