Returns the opacity (as a value from 0 to 1) for a single ``value`` pixel.
Searches through the transparency list, and if a match is found, returns

by the stored transparency value.

the opacity corresponding to the values. Returns 1 if no matches are found.
If any of the red, green or blue values are NaN, 0 will be returned.
