Fair enough. Compared to "mine" though it looks a bit rougher around
the edges when used in a mintty window frame with dark background. In
particular, some of the corner pixels stick out and the wedge has more
pronounced stepping. (See attached pic.)

I wonder whether this is due to resizing algorithm. Can you be
bothered to try different scaling algorithms, or send me the orignal
so I can have a go with Paint.net (which says it uses
"supersampling")?
