+Subject: [PATCH] Emit QScreen::geometryChanged when the logical DPI changes
+
+Add the missing call to QScreenPrivate::emitGeometryChangeSignals()
+along with an emission of physicalDotsPerInchChanged()
+since that is calculated from geometry and physical size.
+
+Rearrange the code in
+QGuiApplicationPrivate::processScreenGeometryChange()
+to prevent duplicate emissions of geometryChanged(),
+physicalDotsPerInchChanged() which this change would introduce.
+
+Amends 5290027e3bab75f14fc0a2b7c206594d9cb91e76.
