Given a 2D array depciting some image to mask out
e.g. a box or a name or a picture of peeve
shrink or fatten it up to fit the shape of our field/grid
dimensions must be at least.... 4 x 4 ? e.g.
. . . .
. x x .
. x x .
. . . .
The players on the field should never write to
the 'x'd out areas.
but our grid will probably be larger than this...
so what is the maths behind making this fit properly?
e.g. a 4 x 4 mask supplied for a 64 x 64 grid
let's start small and just double it
. . . . . . . . . . . . . . . . . . . . . . . .
. . . . . . . . . x x x x x x . . . . . . . . .
. . . . . . . . . x x x x x x . . . x x x x . .
. . . . . . . . . x x x x x x . . . x x x x . .

bad good
I think the result where we look at the proportionality works best.
The first transformation has a single border like the original,
and the second maintains the proportions (e.g. 50%).
What happens when it's more awkward?

I still like the second transformation.
So I guess when taking 1/2 of an odd, round down?
