\section{Fading Library}
\label{section-library-fadings}
\begin{pgflibrary}{fadings}
The package defines a number of fadings, see
Section~\ref{section-tikz-transparency} for an introduction. The
\tikzname\ version defines special \tikzname\ commands for creating
fadings. These commands are explained in
Section~\ref{section-tikz-transparency}.
