Right now, if you have a position change so that the gradient is not centered, the gradient gets clipped when you have farthest-side or *-corner, but for closest side the gradient just gets smaller as you get closer to a side, and disappears altogether (except for the last stop) if you align the center with an edge.

If you wanted the old behavior you could still achieve it through the gradient sizing, e.g. 'radial-gradient(-12.5% -25%, 75% 50%, white, black)' (I think). But I think the clipping behavior would be more useful more often.

I prefer to not change the functionality now unless there's a horrible
mistake that we've missed up to now.  This doesn't seem like a
horrible mistake, but rather just a feature request.  I'm totally cool
with working on this problem in level 4.

For now, let's just finish up the discussion on a more literate syntax
and then finish things at this level.  As soon as we move to LC I'll
open a real ED for level 4, and we can address better implicit-sizing
keywords there.

Is that cool?
