Specifies the miter limit. When two line segments meet at a sharp angle
and miter joins have been specified for 'lineJoin', it is possible for
the miter to extend far beyond the thickness of the line stroking the
path. The miterLimit' imposes a limit on the ratio of the miter length to
the 'lineWidth'.
