Hash fills (with PitchAngleDistribution)

[jbfaden]

Sadie would like to make a pitch angle distribution with hashed regions, where instead of filling a region with an opaque color, a hash (https://stackoverflow.com/questions/28755265/cairo-fill-a-polygon-with-a-hatch-pattern) is used to fill in 50%. This isn't possible with any of the renderers, but a custom renderer could make the plot. Also I'm pretty sure there's an example that shows how to fill with a hash using Java2D graphics.

This was done and she used the mode in her AGU 2022 presentations. It looks like a new Renderer "BoundsRenderer" was added to support this.
