Ballpen style

Illustrious already does a decent job with ballpoint_pen_(medium) and pen_(medium), but it also causes random pens to be included in the image. It really started to annoy me, so I decided to make a model for it.

Trigger is p3nstyle and should be combined with monochrome, greyscale unless you want to try to add color. Avoid using linear hatching for color images, it seems to remove the color.
