// Library initialization:
//
// In a multithreaded program, staticInitialize() must be called once
// during startup, before the program accesses any other functions or
// classes in the IlmImf library.  Calling staticInitialize() in this
// way avoids races during initialization of the library's global
// variables.
//
// Single-threaded programs are not required to call staticInitialize();
// initialization of the library's global variables happens automatically.
