/**
@file uemf_endian.c
@brief Functions for converting EMF records between Big Endian and Little Endian byte orders.
EMF files use Little Endian order.
On a Big Endian machine the data must be converted to/from Little Endian when it is writen to/read from a file.
On a Little Endian machine no conversion is required, but it is good to be able to test the routines on either platform.
When "torev" is true these routines convert from the native byte order to the reverse.
When "torev" is false these routines convert from the reverse byte order to the native.
Routines that do not use that variable swap byte order, and the way in which they do so does not depend
on the native byte order.
The only function here which should be called directly is U_emf_endian(), and then,except for testing purposes, only on a BE machine.
Many variables are initialized to zero even though they will always be set because
some versions of gcc give spurious "may be used uninitialized" warnings otherwise.
