Hi Dr. Olaf,

Thanks for all your work in clearing up issues about SMIL animation. It is
very useful.

I have a quick question about the following statement:

Is the neutral element for scale 0,0? I thought it would be 1,1 based on the
identity matrix.

I want to clarify this behaviour because I have noticed that a number of
implementations use 0,0 and this seems incorrect to me.
