CSS question: how are these effects done?

reading through the source, I find references to

table style="filter:glow(color=blue)

and

TABLE STYLE="filter:Shadow(color=aqua, strength=1)

Although its offensively overdone, I'd like to learn more about it. I can't find anything in the included stylesheet. Am I missing something obvious?
