Review request for Plasma and David Edmundson.


Repository: plasma-workspace


Description
-------

This adds a global function qreal screenPixelRatio(int screen) to the desktop scripting API to complement screenGeometry(). Since we don't do per-screen scaling in Plasma currently the implementation ignores the argument. It's otherwise matching Units::devicePixelRatio.

If this becomes available, I can use it in the default panel layout script to scale the default panel thickness, which is currently unscaled - i.e. when Plasma scales up on a hi-dpi screen the panel will be initialized to be tiny anyway, which is a pretty egregrious papercut on hidpi systems.

Testing
-------

Adjusted layout script, determined it works nicely.


Thanks,
