[whatwg] gradient edge case

While on the topic, it seems like reflected linear gradients would be quite
handy -- insert an "edge" into the stop-sequence and then reflect or repeat
from there.

Subject: [whatwg] gradient edge case


Currently the canvas spec specifies the following:

If x0 = x1 and y0 = y1, then the linear gradient must paint nothing.


If x0 = x1 and y0 = y1 and r0 = r1, then the radial gradient must paint

Why is this? It seems that the gradient should just be a line or circle that
has the first colorstop's on the left/inside and the last colorstop's color
on the right/outside.
