by a space that is either `0-100%` or `0.0-1.0`. An `offset` of `0` is implied and the default. A simple example
of colorizing alpha into a "rainbow" is `colorize-alpha(blue,cyan,lightgreen, yellow, orange, red)`. An example of
using offsets and the variety of supported color encodings is to produce a ramp which sharp contrast between `blue`
and `cyan` is `colorize-alpha(blue 30%, cyan, yellow 0.7 , rgb(0%,80%,0%) 90%)` (#1371).
