- * NOTES
- *
- * These functions are primarily involved with metafile playback or anything
- * that touches a HMETAFILE.
- * For recording of metafiles look in graphics/metafiledrv/
- *
- * Note that (32 bit) HMETAFILEs are GDI objects, while HMETAFILE16s are
- * global memory handles so these cannot be interchanged.
- *
- * Memory-based metafiles are just stored as a continuous block of memory with
- * a METAHEADER at the head with METARECORDs appended to it. mtType is
- * METAFILE_MEMORY (1). Note this is identical 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). I've copied this for 16bit compatibility.
