v2.0

Release version 2.0

This is a major update, almost a complete rewrite. A lot has changed,
including the name, interface and core functionaltiy. The intent remains
more or less the same.

Why the change: see c941877.

What changed:
	* Stop tweaking the text layer; act directly on the canvas
	* Properly apply a color scheme: preserve monotones and accents
	* Accurate color transformations based on color science
	* Process/leave images instead of show/hiding them
	* Move the UI to its own separate (accessible) toolbar
	* Remove the PDF.js wrapper; this is now addon-only

So we lose on changing fonts, but gain big on changing colors. (In fact
I had come across some PDFs with really good fonts and that partially
prompted this rewrite.) The wrapper should have been in its own repo
from the beginning.

Way forward:
	The project has now taken a concrete shape; more drastic changes
are not likely. Next step would be to implement some left-out features,
like handling gradients and patterns.
