Actually, that's kind of what you already have. If you had an actual  
pixel-based image with a 45 degree gradation in it, that angle would  
normally change as you stretch it one way or another. But in your  
proposal it doesn't. it constantly changes relative to itself (not  
relative to the background) as you stretch the box, in ways that  
static images do not. If you have a corner-to-corner gradient, on the  
other hand (not a specified angle), then your proposed gradient is  
resizing more like a static image would (the angle changing based on  
the background-size).

So my proposed change doesn't actually introduce new behavior, it just  
changes how you would specify those behaviors.
