_Content coming soon._ This chapter composes motif layouts, region analysis, clipped cells,
configured direction/shape closures, and cultural/geometric texture generators. It explicitly
separates texture path generation from the later decision of how those paths are sewn.

<Run>{`import std.shapes.ellipsepath as ellipse
import std.textures.truchetpaths as truchet

let region = ellipse(35, 25)
for path in truchet(region, 7) [
up setpos(first(path)) down
sewpath(path)
]`}</Run>
