e86db85cd2 color: Support the CSS hsl() notation
Since we support the rgb() and rgba() notations we might as well also
support the hsl() one.

ab6da347f6 color: Support CSS color definitions
The CSS Color Module 3, available at:

  http://www.w3.org/TR/css3-color/

allows defining colors as:

  rgb ( r, g, b )
  rgba ( r, g, b, a)

along with the usual hexadecimal and named notations.

The r, g, and b channels can be:

  • integers between 0 and 255
  • percentages, between 0% and 100%

The alpha channel, if included using the rgba() modifier, can be a
floating point value between 0.0 and 1.0.

The ClutterColor parser should support this notation.

The clutter_color_add() and clutter_color_subtract() functions are
lacking unit testing to catch eventual regressions.

c7d50083ec [color] allow alpha to be omitted when converting to color from string
Parse #rgb and #rrggbb in addition to forms with the alpha channel
specified. This allows conversion of colour strings from documents such as
CSS where the alpha channel is not specified when using '#' notation.

This patch also adds the relevant conformance test.

db2fda9c43 [tests] Add RGB<->HLS roundtrip test unit
The ClutterColor conformance test should have a unit for verifying
the RGB<->HLS conversion code, especially the ability to roundtrip
between the two colorspaces.
