Infers what a series draws from the path cache uPlot left on it.
uPlot's builders each return a path object whose flags say how a band
fill is clipped against it, and they differ in exactly the way needed:
uPlot.paths.bars leaves 0, uPlot.paths.points leaves 3, and the
linear, stepped and spline builders leave 1. A series whose paths
returns nothing -- the documented way to draw points only -- leaves null.
The cache exists only once the series has been drawn, so a series that is
hidden, or a chart that has not drawn yet, reads as a line: the default a
uPlot series is drawn as.
