% This sub-module covers more-or-less the same ideas as
% \texttt{pgfcoregraphicstate.code.tex}. At present, equivalents of the
% following are currently absent:
% \begin{itemize}
% \item \cs{pgfsetinnerlinewidth}, \cs{pgfinnerlinewidth},
% \cs{pgfsetinnerstrokecolor}, \cs{pgfsetinnerstrokecolor}: Likely to
% be added on further work is done on paths/stroking.
% \end{itemize}
%
% \begin{variable}{\g_@@_linewidth_dim}
% Linewidth for strokes: global as the scope for this relies on the graphics
% state. The inner line width is used for places where two lines are used.
% \begin{macrocode}
\dim_new:N \g_@@_linewidth_dim
% \end{macrocode}

%
% \begin{variable}{\l_draw_default_linewidth_dim}

\dim_set:Nn \l_draw_default_linewidth_dim { 0.4pt }

% layer.
