Double-precision geocoding

Goals

• The following Java interfaces and classes currently operate on 32-bit floats: GeoCoding, GeoPos, PixelPos. Derived classes such as TiePointGeoCoding also perform their computations using 32-bit floats, while others, e.g. PixelGeoCoding use 64-bit internally.
• Many hires applications require 64-bit precision both for internal computation and in the final delivery of results.
