In order to write logic for visual content on the screen, a simple start would be the ability to express a condition like:

Take a histogram of the area [x, y, width, height]. Is this within [distance] of [other histogram]?

As histograms were already implemented with #11 this is actually mostly done. A few tasks remain:

  • Allow script authors to write literal histograms. Perhaps [:histogram 0xffff...].
  • Allow script authors to generate a histogram of a portion of the screen. Perhaps [:histogram-at x y width height].

Add 'compare histograms' command
7f21067 
Issue #32

This adds the ability to:

- Create a histogram given a literal string encoding of one.
- Create a histogram from a rectangle of pixels on the screen.
- A condition comparing whether two histograms are sufficiently
  similar.

This allows branching based on the contents on the screen compared
a known earlier state (which must be precomputed and encoded for now.)
