Summary: In order to have fractional scaling in kwin, we need to communicate it with kscreen, which means changing the data type in our config protocols. This introduces a new method on outputdevice and outputconfiguration to set/request scale as a float. wl_output is and should remain unchanged as an int No urgent rush for reviewing/merging this as it's useless without other changes. Test Plan: Attached unit tests Reviewers: #kwin, romangg Subscribers: romangg, zzag, kde-frameworks-devel Tags: #frameworks Differential Revision: https://phabricator.kde.org/D13601
