Turns a paper_spec() into draw-ready primitives in npc coordinates, spaced
for the given physical panel size. The grob layer (element_sketch_paper())
renders the result; this function stays free of any grid dependency.
Arguments
- kind
A value from
sketch_papers().- width_in, height_in
Panel size in inches (sets the ruling pitch).
- seed
Integer seed (for aged blotches).
Value
A list with ground (fill colour) and zero or more of segs (a list
of homogeneous line groups, each list(x0, y0, x1, y1, colour, lwd)),
dots (list(x, y, r_in, colour)), and blotches (a list of
list(x, y, fill) polygons), or NULL for "none".
