Is there some macro that will tell me what the default PGF line width is? I have tried creating my own macro by cloning
\pgflinewidth before it has been modified, i.e.
\defaultlinewidth seems to be affected by
\pgfsetlinewidth anyway, and change to whatever
\pgflinewidth is. So, the problem is that after I have called
\pgfsetlinewidth, I don't know what the default pgf line width is anymore. Is there some way to get around this?
