Review request for KDE Frameworks and Plasma.


Repository: kwindowsystem


Description
-------

Qt scales down the size of QScreens by the device pixel ratio; we should
make our windowing APIs match.

X (and KWin) deal with device dependent pixels, so everything needs to
be converted when communitcating geometry.

Abstraction happens in the main kwindowsystem so X and Wayland are both
supported.

BUG: 350865
BUG: 350614
BUG: 347951


Diffs
-----

  src/kwindowsystem.cpp 0f8ec0ef470b3a3dcd353a1052dc80ed2bb3f992 

Diff: https://git.reviewboard.kde.org/r/124648/diff/


Testing
-------

Ran yakuake, it looks all right again.
Re-enabled system DPR support in plasmashell (which is currently disabled) and tested notifications and panel struts are all sensible.


Thanks,

David Edmundson
