REVISION SUMMARY Under wayland we support high DPI putting by putting a separation between the logical co-ordinate system and the resolution of rendered assets. I didn't include window decorations in the previous wayland scaling patchset. They were drawn them at a standard resolution, which is implicitly scaled up. This uses the Qt scaling, meaning oxygen and breeze (and others) get perfect high DPI support with zero client changes. Like the window scaling this handles any combination of a 2x scaled decoration being rendered on a 1x screen or vice versa. CCBUG: 384765 TEST PLAN export KWIN_COMPOSE=Q Had two screens of different scales It was the right size on both (as before) Was super-sharp on the fancy screen REPOSITORY R108 KWin BRANCH scaled_decs_qpainter REVISION DETAIL https://phabricator.kde.org/D8504 AFFECTED FILES decorations/decorationrenderer.cpp plugins/scenes/qpainter/scene_qpainter.cpp To: davidedmundson, #plasma Cc: plasma-devel, kwin, #kwin, bwowk, ZrenBot, progwolff, lesliezhai, ali-mohamed, hardening, jensreuterberg, abetts, sebas, apol, mart
