/*---------------------------------------------------------------------------
Set position of the top left corner of the grayscale overlay
----------------------------------------------------------------------------
x = left margin in pixels
by = top margin in 8-pixel units
You may set this in a way that the overlay spills across the right or
bottom display border. In this case it will simply be clipped by the
LCD controller. You can even set negative values, this will clip at the
left or top border. I did not test it, but the limits may be +127 / -128
If you use this while the grayscale overlay is running, the now-freed area
will be restored.
