+Subject: [PATCH] Ensure a pixel density of at least 1 for
+ Qt::AA_EnableHighDpiScaling
+
+Very large 1080p TVs or any display which is running at an abnormally
+low resolution can have a DPI lower than 48, which means that
+qRound(dpi/96) will result in a 0 pixel density, causing critical
+issues for applications using Qt::AA_EnableHighDpiScaling.
+
+Make sure that we always have a pixel density of at least 1 to allow
+applications not having to worry about such displays.
+
