I admit to being Quite Baffled by the new terminology when I tried
using this library a few months ago. Spent a lot of time on WP trying
to find out what everything was! Even something as simple as stating
"yes, just use Colour Double" makes the library seem a lot easier to
plumb in to other things.
A couple of notes:
Section 4.2: "Out of gamut channels be clamped to either to the range
0 to 255" <-- some kind of mix-up here
Section 5: "Note that\n\nOne should avoid dissolving" has a spurious
line break, or an unfinished sentence.
