Note this is indentical to the disk image of a * disk-based metafile - even mtType is METAFILE_MEMORY. * 16bit HMETAFILE16s are global handles to this block * 32bit HMETAFILEs are GDI handles METAFILEOBJs, which contains a ptr to * the memory. * Disk-based metafiles are rather different. HMETAFILE16s point to a * METAHEADER which has mtType equal to METAFILE_DISK (2). Following the 9 * WORDs of the METAHEADER there are a further 3 WORDs of 0, 1 of 0x117, 1 * more 0, then 2 which may be a time stamp of the file and then the path of * the file (METAHEADERDISK).
