The request for SVG or EPS suggests that he has no problem with the look
of the XPM icons; the problem is the size. And scaling of bitmaps is
usually just ugly.

XPM handles transparency just fine -- I have several icons on my screen
right now with transparent areas. What it doesn't do is alpha blending,
which might be what you used for the shadow. PNG supports alpha blending.
The icons look fairly simple, and might not be too hard to just recreate
as PS if the shading were not important. Then they'd scale. I wish I
wasn't such a PS newbie (and so poor at geometry)-: or I'd do it.
Someone who's much more wizardly in PS could probably add the shading back
too.
(BTW I did write a PS program for a scalable "Ethereal 'e'" in case it's
ever useful. The shield behind it has me stumped for now, though.)
