Resolves #5689
If we just drew thicker lines when creating a polygon, then since the centre of the line is the edge, half of each line would be drawn outside the filled polygon.
This PR uses masking to trim the outer half.
Because the image might have any mode, and there are limited modes that can be used as a mask,
fill_im
ink_im
, which extends outside the filled polygonfill_im
as a mask to trim the polygon outline to just the inner part, giving a 1-bitmask
.mask
to paste only the inner part on the original image.
