It's not really very hard.
There's a blub in the Help in the section called "Controlling the Appearance of Points in a Drawing" that lists the order of things, but it's a bit difficult to parse. And it doesn't warn you about the bugs...
I agree a nice graphical representation would probably lay it out in an easy-to-understand manner. It shouldn't really take very long to put something together, but I don't have time now. I can probably get something put together in the next couple of days, unless someone beats me to it. It really is rather straight-forward once you get the hang of it.
