Btw, the reason this happens is due to _really_ poor PNG support in IE (but
not PocketIE or MacIE, go figure). Truecolor transparent PNGs come out all
black. There's an IE-specific trick
(http://webfx.eae.net/dhtml/pngbehavior/pngbehavior.html), but it fails on
https:// addresses due to another IE bug. Best solution is to just swap out
dithered, indexed, transparent PNGs when detecting x86/IE, or if the page is
static, just using such always.
