Make Crosshatch Image (vuo.image.crosshatch)

Creates a crosshatch pattern from an image.

• Background Color and Line Color — The base colors used to create the crosshatch pattern. When multiple lines overlap, the Line Colors are blended subtractively.
• Threshold — The base cutoff point between dark (0) and light (1). The lines are divided into 4 groups (downward slope even and odd, and upward slope even and odd), and this Threshold value is scaled for each group (1x, .5x, .75x, and .3x, respectively). Colors that fall below each scaled threshold are drawn with Background Color; colors that fall above are drawn with Line Color.
• Width — The width of each diamond of the crosshatch pattern, in Vuo Coordinates.
• Center — The position of the center diamond.
• Coverage — The portion of each diamond covered by Line Color, from 0 (hairline) to 1 (fully covered).

Thanks to Brad Larson and Martinus Magneson for the GLSL implementation this node is based on.
