Brush Box and Border should have Pixel margins

When a Brush is specified as Box or Border, the Margins are specified as percentages. which doesnt make sense if you specify the Image/Material in Pixels.
Can we please change this for pixel perfect borders?


Feb 2021, borders are still broken, because no matter what you type there you get 3 borders of width 1px and one random border of width 2px

Got it, seems that 1 pixel = 0.03125
