Summary: Qt's touch event API is rather difficult and complex to implement. As none of KWin's internal windows supports multi-touch gestures yet, this is going the easy route and just simulates a left mouse button press. If in future need arises for touch gesture support on KWin's internal windows, this can be added. Test Plan: Tested on exopc with DebugConsole and auto test Reviewers: #plasma Subscribers: plasma-devel Tags: #plasma Differential Revision: https://phabricator.kde.org/D1661
