Thanks. I'll start applying some parts of the patch shortly, but here
are a few points worth discussing:
1. Renaming color-rgb->hsv to color-rgb-to-hsv, etc.
The latter is a bit more in line with other Emacs Lisp function
names, though we do have a few named "X->Y".
Any thoughts from Emacs developers? I am not sure myself.
2. Returning HUE in [0,1], rather than radians, by default.
If we do this, I'd rather not add a separate *-radians function; we
should just decide on whether Emacs should represent hue as [0,1], as
radians, or as [0,360], and use that everywhere.
For what it's worth, the Gimp, the Java color library, and the
Eclipse API all use [0,360]. Maybe we should do follow suit. Any
objections?
3. The functions for incrementing color components don't look very
useful to me. Surely it's simple enough for a Lisp program to
increment a member of a list. Is there any real world example of a
program using this part of hexrgb?
