-+/* Quartz will clamp input values to the input range.

-+ Our stops are all in the range 0.0 to 1.0. However, the color before the
-+ beginning of the gradient line is obtained by Quartz computing a negative
-+ position on the gradient line, clamping it to the input range we specified
-+ for our color function, and then calling our color function (actually it
-+ pre-samples the color function into an array, but that doesn't matter just
-+ here). Therefore if we set the lower bound to 0.0, a negative position
-+ on the gradient line will pass 0.0 to ComputeGradientValue, which will
-+ select the last color stop with position 0, although it should select
-+ the first color stop (this matters when there are multiple color stops with
-+ position 0).
-+
-+ Therefore we pass a small negative number as the lower bound of the input
-+ range, so this value gets passed into ComputeGradientValue, which will
-+ return the color of the first stop. The number should be small because
-+ as far as I can tell, Quartz pre-samples the entire input range of the color
-+ function into an array of fixed size, so if the input range is larger
-+ than needed, the resolution of the gradient will be unnecessarily low.
