There are at least two problems.  First, there is compatibility with Matlab, 
and second, the output rendered by the print() function will be noticeably 
different.

I took a look at the manual.  I think the confusion is due to the examples 
chosen.  The manual gives an example using defaultlinecolor.  The property name 
is "color" and the object type is "line".  There is no "defaultlinewidth", but 
there is a "defaultlinelinewidth" and could be a "defaultaxeslinewidth", a 
"defaultpatchlinewidth", etc.
