/*
 The viewport<->desktop matching is a bit backwards, since NET* classes are the base
 (and were originally even created with the intention of being the reference WM spec
 implementation) and KWindowSystem builds on top of it. However it's simpler to add watching
 whether the WM uses viewport is simpler to KWindowSystem and not having this mapping
 in NET* classes could result in some code using it directly and not supporting viewport.
 So NET* classes check if mapping is needed and if yes they forward to KWindowSystem,
 which will forward again back to NET* classes, but to viewport calls instead of desktop calls.
