Linocut.Cache (Linocut v0.1.3)

Rasters rendered once and kept on disk, under $XDG_CACHE_HOME/linocut or ~/.cache/linocut.

headings = Linocut.Cache.fetch("ship/headings", "2", fn -> Linocut.headings(points, 64, size: {16, 16}, fill: :white) end)

key may contain slashes; fingerprint is any string that changes when the render should. The render function may return one raster or a list of them; either comes back the same shape, with dense pixel buffers.
