* Enhanced metafile functions
* Copyright 1998 Douglas Ridgway
* 1999 Huw D M Davies
*
*
* The enhanced format consists of the following elements:
*
* A header
* A table of handles to GDI objects
* A private palette
* An array of metafile records
*
*
* The standard format consists of a header and an array of metafile records.
