Change status bubble rendering at hidpi and when there is no client edge

The recently removed client edge on Windows 10 made the status bubble
overlap the window edge. This patch clips out the bubble border when the
bubble is docked, and leaves it unchanged when it's floating. Also made
the border always 1 pixel even at hidpi to make it look more consistent
with the material UI.
