Screen has 3 parameters:
- physical size
- screen size (or screen geometry)
- available geometry
Before this patch, they were reported in 3 different methods. Screen
size update and available geometry update both were generating the
"screen geometry changed" event, that updated the user-visible
parameters. As a result, at some point we could end up in an
intermediate state, when screen size was already updated, but
available geometry was not yet updated.
This was specially visible while changing the screen orientation:
at some point screen geometry could be reported for the new
orientation, while the available geometry - still for old orientation.
This patch introduces a new method to set all geometry-related
parameters together and generate only one "screen geometry changed"
event. This allows to maintain consistency between 'geometry' and
'availableGeometry' properties of QScreen.
