* Class: mxLine

* Constructor: mxLine

* Constructs a new line shape.
*
* Parameters:
*
* bounds - <mxRectangle> that defines the bounds. This is stored in

* stroke - String that defines the stroke color. Default is 'black'. This is
* stored in <stroke>.
* strokewidth - Optional integer that defines the stroke width. Default is
* 1. This is stored in <strokewidth>.
