	{spec,dspec,len}	specify a maximum length for any streamline

When explicit initial points are given in the form , StreamPlot and related functions effectively follow the flow of the vector field forward and backward from each point.
In the form , the minimum distance d between streamlines is given in ordinary coordinates, and applies in all directions.
In the form , len gives the total length of the streamlines to generate forward and backward from each explicit initial point specified. The length len is measured in ordinary coordinates.
The parameters d and len can be specified in the form Scaled[s], representing a fraction of the diagonal of the whole plot.
