"""
Overlays the printable areas onto the src PDF, this is so the code can check for a presence of non white in the
areas outside the printable area.
Our overlay function draws four areas in white. Logo, address, service address, and the body. Logo is the area
above the address area. Service address runs from the top right, down the side of the letter to the right of
the address area.
This function subtracts/adds 1mm to make every boundary more generous. This is to solve pixel-hunting issues where
letters fail validation because there's one pixel of the boundary, generally because of anti-aliasing some text.
This doesn't affect the red overlays we draw when displaying to end users, so people should still layout their PDFs
based on the published constraints.
