New (and last) working draft for Color

The CSS working group published what it hopes will be the last working
draft of "CSS3 module: Color" (or "css3-color" for short). As usual,
comments are welcome on this mailing list, <www-style@w3.org>.

The deadline for comments is May 17, after which date the working
group will analyze the comments, answer those not yet answered, and
decide whether to propose the draft as a "W3C Candidate
Recommendation" or not. The URL of the draft is:

    http://www.w3.org/TR/2002/WD-css3-color-20020418

For those of you who have read the previous draft, here is a short
list of the most important changes:

  - All properties now have an entry for "computed value" that defines
    how the computed value of a property is derived from the
    specified value in the style sheet.

  - The 'opacity' property has an optional second value, that
    indicates how important it is that the UA honors the property. This
    is meant to help browsers on (small) devices whose hardware only
    allows one or two elements to be transparent. Values are '1' (very
    important), '2', '3',... 'none' (very unimportant)

  - 'transparent' is defined to mean "transparent black"
    (rgba(0,0,0,0)) instead of "transparent white." The color may seem
    unimportant, but has to be defined when the property is animated
    with SMIL, e.g., to become progressively less transparent.

  - The first argument of 'hsl()' is now a number without a unit. This
    way colors are easier to compare, and nobody wanted to specify the
    hue in 'rad' instead of 'deg' anyway.

  - The 'flavor' property is not deprecated anymore. Instead, it is
    left to profiles, such as the Mobile Profile, to define whether
    they support a property or not.

There is no test suite yet.
