[x,y] = polybool('union', [0 0 1 1], [0 1 1 0], [], [])
The polybool function returns the first input pair: [0 0 1 1], [0 1 1 0]. Now
consider the 'intersection' operation:
[x,y] = polybool('intersection', [0 0 1 1], [0 1 1 0], [], [])
The polybool function returns [], [].
Compatibility Considerations
In previous releases, if one or both pairs of input vertex arrays were empty, the
polybool function would issue an error.
