I read in the specification that the patternTransform attribute:

"contains the definition of an optional additional transformation from the 
pattern coordinate system onto the target coordinate system . This 
additional transformation matrix is post-multiplied ",

and:

"If attribute 'patternTransform' is not specified, then the effect is as if 
an identity transform were specified. ".

What's an identity transform? Does it mean that if patternTransform is 
specified,  implementations are allowed to bitmap the tile and re-sample it? 
That's the impression I have with Opera, Firefox and Webkit. From what I can 
see, only IE9 seems to apply transformations correctly. The result is kind 
of acceptable in Opera and Firefox, but really bizarre in Webkit.

You can check some results here:
