/** An %RGBA color.
 * The %RGBA class is a convenient way to pass colors around.
 * It's based on cairo's way to deal with (possibly translucent) colors and mirrors its behavior.
 * All values are in the range from 0.0 to 1.0 inclusive.
 * So the color (0.0, 0.0, 0.0, 0.0) represents transparent black and (1.0, 1.0, 1.0, 1.0) is opaque white.
 * Other values will be clamped to this range when drawing.
