Display freelook speed and zoom in units in the 3D editor viewport

Browse Source 
Now that the 3D editor grid is infinite and adjusts its step automatically,
this helps people get a better sense of scale when moving around in the
3D viewport.

This also fixes the indicator bar drawing on hiDPI displays.
