ps_setmiterlimit — Sets the miter limit
If two lines join in a small angle and the line join is set to PS_LINEJOIN_MITER, then the resulting spike will be very long. The miter limit is the maximum ratio of the miter length (the length of the spike) and the line width.
Resource identifier of the postscript file as returned by ps_new().
The maximum ratio between the miter length and the line width. Larger values (> 10) will result in very long spikes when two lines meet in a small angle. Keep the default unless you know what you are doing.
TRUE in caso di successo,
FALSE in caso di fallimento.
