/**
 * Abstract class for Ground Control Point Transformers.
 *
 * This class contains all logic to transform geometries
 * made available trough the GeneralGcpTransform and GcpTransform classes.
 *
 * The extending GeneralGcpTransform class handles the general case where:
 * - We read in Ground Control Points using the GeneralGcp type, with `source` and `destination` fields.
 * - We use the terms 'forward' and 'backward' for the two transformations.
 * - Both source and destination space are exected to be 2D cartesian spaces with the same handedness (x- and y-axes have the same orientations).
 *
 * The extending GcpTransform class handles the typical Allmaps case where:
 * - We read in Ground Control Points using the Gcp type, with `resource` and `geo` fields.
 * - We use the terms 'toGeo' for the 'forward' transformation and 'toResource' for the 'backward' transformation.
 * - The `differentHandedness` setting is `true` by default, since we expect the resource coordinates to identify pixels on an image, with origin in the top left and the y-axis pointing down.
