Re: Non-quadratic form of whiteout

[Lukas-Fabian Moser]

Addendum: Of course, "quadratic" is not the right word. What I mean by 
it is that the horizontal and vertical protrusions of the whiteout box 
around the actual rectangular hull of the object are equal. For, e.g., 
noteheads, this /does /lead to an (almost) quadratic shape.
