Animated example: text scales in steps on WebKit

SVG (and HTML) font sizes in WebKit are rounded (wrongfully) creating imprecise layout or making measuring text difficult/impossible. 
In the attached test case and animated inline SVG with the text not scaling smoothly.

Seems to be fixed in STP174.

@Myles - your fractional font size fix might have helped here?
