Clipper.JoinBevel (gb.clipper)
Const JoinBevel As Integer = 0
Bevelled joins are similar to
squared joins except that squaring won't occur at a fixed distance. While bevelled joins may not be as pretty as squared joins, bevelling is much easier (i.e. faster) than squaring. And perhaps this is why bevelling rather than squaring is preferred in numerous graphics display formats (including SVG and PDF document formats).
