Detailed Description
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.
