Graphics context Docs

Hi all,

I've started the very beginning of poking around with GraphicsContext. 
I'm hoping to make use of it for FloatCanvas. However, I'm unable to 
find any overview-type docs. Is there such a thing anywhere?

Anyway, the topic at hand:

I'm trying to figure out how to draw a line (maybe a polyline, actually) 
that "fades away" -- that is, it starts alpha=255 and ends at alpha=0.

I found CreateLinearGradientBrush(), which is almost what I want, but 
since I'm drawing a line, not really. Are there any Gradient Pens?

Otherwise, I guess I have to draw a really skinny polygon with a 
GradientBrush, but that sure feels kludgy.

-thanks,
-Chris
