White lines in conformal mode? #4
Description
The readme suggests that for a conformal grid, both the constant phase and constant magnitude are shaded darker. But some other phase portraits use white for one of these. For example, in a Mathematica StackExchange https://mathematica.stackexchange.com/questions/7275/how-can-i-generate-this-domain-coloring-plot/7359 and on Wikipedia https://en.wikipedia.org/wiki/Domain_coloring. Should white lines be an option?
