  23  * NOTES
  24  *
  25  * These functions are primarily involved with metafile playback or anything
  26  * that touches a HMETAFILE.
  27  * For recording of metafiles look in graphics/metafiledrv/
  28  *
  29  * Note that (32 bit) HMETAFILEs are GDI objects, while HMETAFILE16s are
  30  * global memory handles so these cannot be interchanged.
  31  *
  32  * Memory-based metafiles are just stored as a continuous block of memory with
  33  * a METAHEADER at the head with METARECORDs appended to it.  mtType is
  34  * METAFILE_MEMORY (1).  Note this is identical to the disk image of a
  35  * disk-based metafile - even mtType is METAFILE_MEMORY.
  36  * 16bit HMETAFILE16s are global handles to this block
  37  * 32bit HMETAFILEs are GDI handles METAFILEOBJs, which contains a ptr to
  38  * the memory.
  39  * Disk-based metafiles are rather different. HMETAFILE16s point to a
  40  * METAHEADER which has mtType equal to METAFILE_DISK (2).  Following the 9
  41  * WORDs of the METAHEADER there are a further 3 WORDs of 0, 1 of 0x117, 1
  42  * more 0, then 2 which may be a time stamp of the file and then the path of
  43  * the file (METAHEADERDISK). I've copied this for 16bit compatibility.
  44  *
