	Downloads images from my notes at HackMD.io.
	Creates new MD files with relative path image links.

	Uses the links from the 'notes-backup' files downloaded with
	download_notes.py (run it first)

	I was skipping images hosted from my dreamhost account
	but decided to download them too.

	''' Read and parse SVG files returning a shapely GeometryCollection containing the paths and primitives found.
	Transforms are applied and all shapes are returned in the SVG root elements coordinate space. Primitives (rect,
	circle and ellipse) are converted to equivalent paths, and only shape outlines are rendered, stroke properties
	have no affect and are discarded.

	Curved paths (arc and bezier commands and rounded rect, ellipse and circle elements) are linearized using a
	naive approach that attempts to create enough segments to reduce maximum distance to the curve to below a
	certain threshold, although this is probably not very efficient and most likely implemented in a fairly
	broken way.'''

	Interesting program that shows your webcam's image as ASCII text. Runs in realtime, producing a stream of
	images so that it is actually animated ASCII text. Wild stuff that came about from a post on Reddit of all
	places. The software bits that turn the image into ASCII text were shamelessly taken from this gist:
