Argh, I keep missing these calls!  They're on my calendar now, so I
should get next week.

My approach for degenerate cases has been to specify the limit image,
so the behavior is as continuous as possible.  I consider any behavior
that is sensitive to rounding errors a bug.

For example, if a repeating gradient approaches 0 distance between
first and last stops, it will assume the average color on an
infinite-resolution device.  Thus, on our finite resolution devices,
when the distance is small enough that we can't faithfully render it
any longer, we should just render the average color.

I have similar cases for repeating radial gradients that approach zero
width or zero height.

In this case, when the focus approaches the edge of the shape, the
image converges to a half-plane of circles, and a half-plane of
average color.
