Do you think it is reasonable to use "letter-spacing: 3px; font-kerning: 
none" in place of "kerning: 3px" for SVG content?  If we are in the 
situation where we could drop "kerning" in favour of authors using a 
combination of font-kerning and letter-spacing, should we do that?  Or 
is letter-spacing something different enough from kerning adjustment 
that it should be kept separate?
