# The <code>line_width=</code> method sets the stroke width for subsequent
# stroke calls.

# Since Ruby assumes that an unknown variable on the left hand side of an
# assignment is a local temporary, rather than a setter method, if you are using
# the block call to <code>Prawn::Document.generate</code> without passing params
# you will need to call <code>line_width</code> on self.
