The current opacity value (0 fully transparent, 65535 fully opaque). You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Sets the 'previous' alpha to be alpha . This function should be called with some hesitations, as it might seem confusing to have that alpha change.
