[CSS3Units] angles should not be normalised

CSS3 Values and Units says this in 3.4.5:

[[[
Angle values should be normalized to the range 0-360deg by the user  
agent. For example, -10deg and 350deg are equivalent.
]]]

I propose this be removed. User agents should not normalize the  
values, since the direction of rotation can be important, or even the  
fact that it occurred (for example, rotating 360deg is not the same as  
staying still, even though you end up at the same place).
