v2.21 Program Icon - Request for larger version

This hardly ranks as a bug, more of a request.....

Can we get a high resolution / larger version of the program icon?

The icon included in the program is 48x48 and it doesn't look all that great when used at larger sizes in apps like ObjectDock.

I found this: http://www.wincustomize.com/skins.aspx?skinid=14192&libid=29 but I'd prefer a 256x256 good quality version of the original if that's possible.
