curve_fill

For area/ribbon/density geoms: converts a curved boundary (list of Bezier
control-point sets) into a polygon approximation, then applies <code>sketch_fill</code>.

Provides 'ggplot2' geoms that render with a hand-drawn, sketchy
aesthetic: roughened strokes, double-pass lines, and hachure, cross-hatch,
zigzag, and dots fill patterns. Implemented as pure-R 'grid' grobs wrapped
in 'ggproto' geoms, composable with aes(), stats, scales, and faceting.
Works on every R graphics device (PDF, PNG, SVG, screen) with no browser
dependency. Algorithms are reimplemented from the published 'rough.js'
algorithm description (Shihn, 2020,
<https://shihn.ca/posts/2020/roughjs-algorithms/>) and Wood and others
(2012, <doi:10.1109/TVCG.2012.262>); see the NOTICE file in the package
