Hatch or stripes filling for shapes

[benoit-dd]

At the moment it is only possible to fill a shape with a single color, with or without transparency

solution I'd like possibility to have a hatch color style

Thin stripes of color with transparent background

additional possibilities:

• Set distance between stripes
• Set stripes orientation (horizontal, vertical, 30/45°), by preset or free angle value (+/-(0-90))
• 2 large stripes of different colors filling everything
• parallel stripes or crossed

If we go that way, it would be great to have different patterns to be able to handle color blindness (deuteranopia, protanopia, tritanopia, etc).

A few options:

• https://riccardoscalco.it/textures/ (but includes d3…), at least a nice overview of texture usages
• https://github.com/teastman/Leaflet.pattern (allows to define SVG patterns once and then reuse them)
• https://github.com/lwsu/leaflet-polygon-fillPattern/tree/master (very simple, use images as pattern)
• https://github.com/samanbey/leaflet-hatchclass (only hatch)
