Support different endian modes when reading and writing the metafile.
To support different endian modes, rather than just writing the structures directly to a file via fwrite( &emr, ...), we have to write each element of the structure separately, swapping bytes as necessary. datastream supports this. Remarkably similar to the QDataStream class from Qt. So, too, for reading.
Constructor for DATASTREAM.

Output an Enhanced Metafile Record header.
Parameters
Output an Enhanced Metafile Text Record.
