I'm okay with requiring basic napkin calculation to handle the case of
knowing what %s you want the stops to be at *and* knowing what length
you want the entire gradient to be.  That's a trivial enough
calculation (I want a 25% stop in a 260px gradient, so 260 * .25 =
65px) that I don't think it's a problem we need to solve.  It's when
an author has to do trig to solve reasonably common cases that we have
a problem.

Can we recall what the use-case was for angle+point in the first
place?  It would, I think, simplify the mental model of things
considerably if that can be dropped.  Then you'd have only three ways
of specifying a gradient - angle, point, and default, and all three
will work intuitively.
