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.
