SetMiterLimit(limit)
limit. This can be
a fractional value. The miter limit is used when the join style is set to #JOINMITER
to determine when to join lines with a bevel and when to join them using a miter.
Note that #JOINMITER is also the default line join style.
When drawing line ends, the length of the miter is divided by the line width and if the result of this division is greater than the miter limit set using this function, lines are joined using a bevel.
Hollywood's default miter limit is 10.
