Making the icons work was a really good idea. But it doesn't seem to work right for me - the icons appear, but only in 2 colours - transparent and white. Presumably the mask is converted correctly but not the icon itself. I checked with xclock, oclock, xditview, xcalc, xload.
It only happens in 32bit colour mode, not in 16bit (1024x768 in each case if that's relevant). XWin -clipboard -multiwindow -emulate3buttons 100 -clipupdates 5 Lev
