Hmm, me neither, actually.

No, but I didn't even try,  because it was >300K.

Going back to the 256x256 PNG I put into the icon though, it's
actually only 16KB, so do find that attached. Also attached is the
52KB 768x768 version exported from InkScape that I'd generated the
smaller ones from by scaling them down in Paint.net.

Which leaves the question how the icon with the 256x256 became so big.
I'd used a Cygwin build of 'icotool' from 'icoutils' for that, which
generally seems very nice for extracting and creating icons. But it
would appear that it doesn't support the .ICO format extension that
allows to embed PNGs directly, instead storing them in whatever less
efficient bitmap format .ICOs have used before.

How do you create icons including a 256x256 version? I haven't managed
to get the 'icobundl' utility that Warren linked to to do it.

$ icobundl -o blank-terminal-256.ico blank-terminal-256.png
blank-terminal-256.png
blank-terminal-256.png
No icons found, wrote empty icon suite
