Drawinglayer hatching

[Chris Sherlock]

Hello all, 

I have been looking into getting hatching working for EMF+ processing. I can see we already have some hatching code that draws diagonal lines, but for the life of me I’m not sure how to extend this to other forms of hatching like dithering (yes, EMF+ requires this). 

Can anyone give me a rundown how the drawinglayer hatching code works so I can extend it?

Other example hatches I need to implement, incidentally, can be found here:
