I have to admit I just quickly glanced at the code and it wasn't
immediately clear to me how it worked. I saw PNGs, but I also saw
reference to SVG's (Scalable Vector Graphics for anyone that might not
know). It makes sense that the growing and shrinking be done with
SVGs, it's tailor-made for such an application. I'm not sure where
the PNGs come in to play either.
Well, the images themselves are PNG. I'm not sure what the svgSrc
attribute is being used for (or what it is). But Firefox can't display
SVG (natively), so it's either taking the SVG and scaling it into PNG on
the server side, or it's just to confuse us ;)
Bzzt! Wrong, sorry. ;-) Firefox 1.5 has native SVG support. The svgSrc
attribute allows you to take advantage of that. Otherwise it will use
the PNGs.
I also wasn't aware that
IE would handle PNG transparency properly, so I'm pretty lost.
It doesn't, by itself. There's some fancy footwork going on behind the
scenes to make this happen. Like I said, these guys know their stuff.
