DOCS: Document pattern file format .val & .vit about seamly2d HOT 2 OPEN

Much of that is outdated info.... other than most of the ToolType tags - which will eventually be updated to reflect the updated tool names. The Seamly2D (and SeamlyMe to a lesser degree) have drastically diverged from the Val schema.

That being said I would just run one of the XML Schema documentation tools out there to generate the schema docs. KISS.

from seamly2d.

Could you give an example of the documentation you would expect ?
I am currently looking into the XML file formats and could contribute something:

Object type

Point

• . single Base point
• .---. endLine Point at distance and angle
• .--.---. alongLine Point at distance along line
• |_ normal Point along perpendicular
• ./ bisector Point along bisector
• /. shoulder Special point on shoulder
• |_\ triangle Triangle tool
• .+. pointOfIntersection Point from X and Y of two other points / Tool to make point of x _y of two other points
• | height Perpendicular point along line
• |/ lineIntersectAxis Point intersect line and axis
• -.- alongLine length="CurrentLength/2" Midpoint between two points

Line

• Line between points
• lineIntersect Point at line intersection

Curve

• .). simpleInteractive Simple curve / Curve tool
• Segmenting a simple curve
• Curve tool which uses point as control handle
• .).).). pathInteractive Curved path / Tool for path curve
• Segment a curved path
• cubicBezierPath Curved path tool which uses point as control handle / Tool cubic bezier curve
• pointOfIntersectionCurves Point intersection curves
• curveIntersectAxis Point intersect curve and axis

Arc

Elliptical Arc

Operations

Line Attributes

typeLine / penStyle

I think here .val and .sm2s files diverge on the typeLine / penStyle attributes
