Detailed Description

Manages a gradient for the unlitGradient shader. In gradient mode, the array of points specifies points along the gradient, from 0 to 1 (inclusive). These do need to be evenly spaced. Simple greyscale: [ { 0.0, black }, { 1.0, white } ] Rainbow (note the gaps around green): [ { 0.000, blue }, { 0.125, cornflower blue }, { 0.250, cyan }, { 0.500, green }, { 0.750, yellow }, { 0.875, orange }, { 1.000, red } ] The gradient will generate a largish texture, so it should be fairly smooth, but the boundaries may not be exactly as specified due to quanitization imposed by the fixed size of the texture. The points must be sorted from the smallest value to the largest. The values must be in the range [0, 1].

Enumerator
kGradient
kLUT	Normal gradient mode. Point.value will be ignored and the colors will be assumed to be evenly spaced. The texture will have only as many pixels as there are points.
