// This is the principal factory method. It accepts a string in one of three formats:
//
// 1. <group>:<code>, for example "EPSG:32615"
// 2. <code>, for example "32615", this is the CRS code ID for the projerection.
// 3. AUTO:<comma-separated spec>, for specifying custom user-defined codes.
//
// Both projected and geographic (Platte Carre) codes are handled.

// IMPORTANT NOTE: Image tie-points cannot be conveyed by an EPSG projection code. The projection
// created here will not be fully initialized for use in rendering imagery.
