Hi All,
 
Section about data normalization,
http://www.w3.org/TR/SVGMobile12/svgudom.html#Attribute_Normalization,
says, according to my reading, that if path data is normalized,
it has to be normalized so that quadratic beziers are transformed
to cubics (Rules T->C, Q->C). Some things like path animation
explicitly require normalization to remove relative coordinates etc.

Conversion from quadratic to cubic form adds a coordinate pair, which
means more memory consumption. 

Is is actually allowed to keep quadratics as is and just expand the
smooth quadratics to normal ones in normalization? If not, why?
 
 
Yours,
