LineStyle()

Creates a new line style.

linestyle = LineStyle(array specification)

Specification element	Type	Contents
1	Array	Parallel components of the line style, where each component is an array as described below
2	Array	Perpendicular components of the line style, where each component is an array as described below
3	NA	Cap style; currently ignored
4	NA	Join style; currently ignored
5	Array	Font icon components of the line style, where each component is an array as described below

Parallel components	Type	Contents
1	Real	Width
2	Integer	Color index (see the notes)
3	Real	Offset from centerline
4, 5, ...	Real	Dash lengths (alternating on and off, optional)

Perpendicular components	Type	Contents
1	Real	Width
2	Integer	Color index (see the notes)
3	Real	Distance from the start of the line before drawing the component
4	Real	Frequency (distance between components)
5	Real	X1
6	Real	Y1
7	Real	X2
8	Real	Y2

Font icon components	Type	Contents
1	String	Name of the font
2	Double	Distance from the start of the line before drawing the component
3	Double	Frequency (distance between components)
4	Double	Offset from centerline
5	Double	Rotation angle
6, ...	Array	One array for each glyph of the form {integer index, integer color}, containing the index of the icon in the font and the color index (see the notes)

A line style.

All sizes and distances are in points.
Passing null for the specification returns the invisible line style.
The specification does not need to include all the elements. You can have one, two, or all five elements.
Passing {{{0, -1, 0}}} returns the solid line style.
Colors indices are 0: Black, 1: White, 2: Red, 3: Green 4: Blue, 5: Light Blue, 6: Yellow, 7: Gray, 8: Dark Gray, 9: Tan, 10: Brown, 11: Gold, 12: Dark Gold, 13: Orange, 14: Dark Orange, 15: Dark Red, 16: Dark Green, 17: Magenta, 18: Purple, or -1 for the underlying color of the line.
A perpendicular component is a line segment drawn from (X1,Y1) to (X2,Y2), beginning after the start distance and repeating based on the frequency. The X coordinates are positions along the line. The Y coordinates are positions across the line, with Y > 0 to the left of the line and Y < 0 to the right of the line.
Width 0 components are drawn using hairlines.

traintracks = LineStyle({{{1, -1, 0}}, {{1, -1, 18, 18, 0, -9, 0, 9}}})

donkeys = LineStyle({,,,, {{"Caliper Miscellaneous", 0, 1.4, 0, 0, {{105, -1}} }}})
