• public Color color { set; get; }
  The selected color.
• public string title { set; get; }

  If this property is set to true, the color swatch on the button is rendered against a checkerboard background to show its opacity and the opacity slider is displayed in the color selection dialog.

Creation methods:

• public ColorButton ()
  Creates a new color button. This returns a widget in the form of a small button containing a swatch representing the current selected color. When the button is clicked, a color-selection dialog will open, allowing the user to select a color. The swatch will be updated to reflect the new color when the user finishes.
• public ColorButton.with_color (Color color)
  Creates a new color button.

• public uint16 get_alpha ()
  Returns the current alpha value.
• public void get_color (out Color color)
  Sets color to be the current color in the ColorButton widget.
• public unowned string get_title ()
  Gets the title of the color selection dialog.
• public bool get_use_alpha ()
