Subject: [PATCH] prefs: Scale preview border

We currently pick up the settings value directly, which is the
border that is used on the actual (i.e. monitor-sized) background.

That's way too big when applied as-is on the preview, so assume a
common monitor size and compute an appropriate scale from that.
