Summary: So far wayland was used by internal clients to submit raster buffers and position themselves on the screen. While we didn't have issues with submitting raster buffers, there were some problems with positioning task switchers. Mostly, because we had effectively two paths that may alter geometry. A better approach to deal with internal clients is to let our QPA use kwin core api directly. This way we can eliminate unnecessary roundtrips as well make geometry handling much easier and comprehensible. The last missing piece is shadows. Both Plasma::Dialog and Breeze widget style use platform-specific APIs to set and unset shadows. We need to add shadows API to KWindowSystem. Even though some internal clients lack drop-shadows at the moment, I don't consider it to be a blocker. We can add shadows back later on.
