This commit adds the ORIGIN_TRANSFORMS class to support Display Origin Transforms in all KiCad applications. Functions are provided to perform four basic types of origin coordinate transforms: * Transform a relative coordinate from internal to display form * Transform a relative coordinate from display to internal form * Transform an absolute coordinate from internal to display form * Transform an absolute coordinate from display to internal form These functions are supported for data types "int", "long long int", and "double". The default implementations for all but "int" simply return their input unchanged; the implementation for "int" invokes the implementation for "long long int". The expectation is that the different KiCad applications will create derived classes from this base class and override the functions as needed. Protected template functions are provided for the standard translations to maintain consistency within the derived classes.
