* @alias module:marching-squares.traceImageRegion
* Trace a closed polygon around a region in a two-dimensional grid. The
* isInside function is called to determine if a given point is inside or
* outside the region.
*
* The starting point MUST be on the edge of the region. Specifically this
* means that among these four calls
* 1. isInside(x-1, y-1)
* 2. isInside(x, y-1)
* 3. isInside(x-1, y)
* 4. isInside(x,y)
* At least one must return falsy and at least one must return truthy. If
* this is not the case, an Error is thrown.
*
* An efficient marching-squares algorithm is used to trace the region,
* using minimal memory and calling isInside() only as neccessary.
*
* @param {int} x - starting x coordinate.
* @param {int} y - starting y coordinate.
* @param {function} isInside - function with signature isInside(x,y) returning
* truthy if the given point is inside the region to trace (for
* example, it is an opaque pixel in a bitmap) and falsy if it is outside
* (for example, it is transparent). The function should be able to handle
* any x and y including negative values "outside the bitmap" (for which it
* should return false).
* @returns {array[object]} array of point objects with x & y properties tracing
* a closed polygon around the region. The first point is NOT repeated
* as the last point. The polygon consists entirely of one-unit-long
* horizontal or vertical segments. Use a polygon simplification routine on
* the results to simplify and/or smooth it.
* (Might I suggest https://www.npmjs.com/package/line-simplify-rdp ?)
