Linear gradients: state of the proposal

To keep the gradients discussion moving, here's a summary of where  
things stand with linear gradients:

* Tab's proposal is at: <http://dev.w3.org/csswg/css3-images/ 
#gradients->
* I raised objections related to the complexity of the proposal, and  
proposed a simpler two-point form with an optional angle: <http://lists.w3.org/Archives/Public/www-style/2009Nov/0050.html 
 >
* Tab said in person that he sees the value of a two-point form for  
linear gradients.
* Dean and Roc question top left being the default. I'm fine with  
center top.
* When the angle form is used, it's unclear if the angle of the  
rendered gradient is invariant under box aspect ratio changes <http://lists.w3.org/Archives/Public/www-style/2009Nov/0071.html 
 >.
* Angles in the gradient proposal (0deg is East, 90deg is North)  
differ from those used in SVG and transforms (angles increase in a  
clockwise direction).

I'm sure radial gradients will raise a similar amount of discussion.
