I tried to think of a way of defining linear gradients such that the  
angle was an
angular offset from the line specified by the two points, but that  
the purpose of specifying the angle in the first place (the use case  
being to
have a gradient at a fixed angle irrespective of box size).

I'd be OK dropping angles from linear gradients. You can always get a  
angle by specifying two points in pixel coordinates; what you lose is  
the ability
to have a fixed angle gradient that automatically fills the box. I'm  
not sure if this
would be a common use case.
