* The #GdkRGBA struct is a convenient way to pass rgba colors around.
* It's based on cairo's way to deal with colors and mirros 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.

* GdkRGBA:
* @red: The intensity of the red channel from 0.0 to 1.0 inclusive.
* @green: The intensity of the green channel from 0.0 to 1.0 inclusive.
* @blue: The intensity of the blue channel from 0.0 to 1.0 inclusive.
* @alpha: The opacity of the color from 0.0 for completely translucent to
* 1.0 for opaque.
*
* The GdkRGBA structure is used to pass around color data. When using it
* as struct members or on the stack, you want to use the struct directly
* and not allocate it.
