From ec462b245fa138a6b036f3db9c960015a36fd828 Mon Sep 17 00:00:00 2001 From: Paul Olav Tvete <paul.tvete@theqtcompany.com> Date: Mon, 22 Jun 2015 12:25:33 +0200 Subject: [PATCH] X11 changes for highdpi Adapt the xcb plugin to work with the new cross-platform high-DPI scaling. Fixes for drag and drop is done in a separate change.
