>+        The CSS spec for all gradients allows for each color stop to have two angles to be used for hints.
>+        This makes pie chart and checkerboard conic gradients much simpler to write.
>+        Any time you want to have a hard line in a gradient, this syntax simplifies the gradient specification.
