## pldata1.pi - test ppolyline_set3_data with a few different
## geometries and widths, with vertex data.  Combinations tested:
## - set of one single-vertex polyline (not expected to draw)
## - set of one multi-vertex polyline
## - set of two single-vertex polylines (also not expected to draw)
## - set of three polylines, of 3, 1, and 4 vertices
