/O number
(Optional) A number in the range 0.0 to 1.0 specifying the constant opacity value that shall be used in painting the background colour specified by B. A value below 1.0 means the window shall be transparent. EXAMPLE 2 Windows behind a floating window show through if the media does not cover the entire floating window. A value of 0.0 shall indicate full transparency and shall make B irrelevant. It shall be ignored for full-screen and hidden windows. Default value: 1.0 (fully opaque).
Qualifier: Optional
