Description of problem:
The up2date panel icon(s) look good in Gnome.  It's a differnt story
in KDE, as the button is part of a larger great area, about twice its
width.  This looks especially odd and bad when you have set you panel
to be tranparent.  

So, the suggestion if very, very simple: make the button transparent
around the edges, not great, so it can blend in with a tranparent
background, like application icons do.  

They're beatifully done up2date icons, by the way.  The blue
checkmark, red updates waiting and green checking icons were very well
done, so hats off to the person who designed them.
