Fix overscan mask being half as thick as it should be

Browse source 
The percent values used for the overscan masks follow the BBC's
guidelines, as in
https://en.wikipedia.org/wiki/Overscan#Overscan_amounts .
However, these measure the per-side width as opposed to the total
percentage of width/height being cut off. Thus, they should not be
divided by two when drawing the mask.
