Thanks for the tip. I checked in a new 152x152 icon with lightgrey
stroke which I blurred before. I resized using the cubic interpolation
because I forgot to set it to linear (no "bilinear" in gimp), but it
looks good to me. If you want to have a look, I uploaded it to
http://cygwin.de/cygwin-standalone-beveled.ico again.
