Re: Interim strategies for no SMIL (and other?) support in IE9

Hi, folks-

Just to clarify, when I said "more functional", I meant specifically for 
the following three features:

1) SVG Fonts: the full profile of SVG Fonts, i.e. SVG fonts with 
arbitrary content, rather than simple path syntax

2) Declarative Animation: ASV had fairly good (though not great) SMIL 
support; performance could have been better, but they had a fairly full 
feature set.  Firefox may have SMIL support, and there is interesting 
stuff going on with CSS animation as well.

3) Filters: ASV had fairly complete filter support, unsurprisingly, 
since many of the filter primitives come from Illustrator and Photoshop. 
  Firefox has made a lot of progress here, actually.

I don't think IE9 will support any of these three, but it (and the other 
browsers) will do other things better than ASV did, like HTML 
integration and hardware acceleration; but these areas of improvement 
aren't the features at risk for legacy content, by definition.

Note: Opera has fairly complete SVG support, so I'm less worried there; 
WebKit also has pretty good SVG support, though Android turns it off for 
now. :(

So, the question remains... how to best manage the transition?
