Is there planned support for animating a path?
e.g. app engine project delivered from here:
http://www.animentor.com/graphics/wavingman.html


Expected:  crude drawing of a body slowly waving an arm over a 10s period
Actual:  static image from time zero

Very useful so far!  An important use case now is delivering animated figures.

I've started this in r899.

Note, however, that this just supports setting 'd' as a discrete value. The neat
thing about animating path is that native implementations interpolate between path
data points specified in different key values. This provides a smooth path
transition. That is a cool effect that still needs to be implemented.

Yeah, Opera is one browser that interpolates between values and the result is quite good.  Discrete values are a 
good start.  This will allow proof of concept and give the idea of what the final animation will look like when 
smoothed out.  A kind of storyboard perhaps.

I updated to the "Beholder" release and the discrete value path animation works as expected.  If I were to 
increase the sampling frequency I could smooth it out (at the expense of file size, of course).  Thank-you.
