10 * These functions are primarily involved with metafile playback or anything
11 * that touches a HMETAFILE.
12 * For recording of metafiles look in graphics/metafiledrv/
14 * Note that (32 bit) HMETAFILEs are GDI objects, while HMETAFILE16s are
15 * global memory handles so these cannot be interchanged.
17 * Memory-based metafiles are just stored as a continuous block of memory with
18 * a METAHEADER at the head with METARECORDs appended to it. mtType is
19 * METAFILE_MEMORY (1). Note this is indentical to the disk image of a
20 * disk-based metafile - even mtType is METAFILE_MEMORY.
21 * 16bit HMETAFILE16s are global handles to this block
22 * 32bit HMETAFILEs are GDI handles METAFILEOBJs, which contains a ptr to
24 * Disk-based metafiles are rather different. HMETAFILE16s point to a
25 * METAHEADER which has mtType equal to METAFILE_DISK (2). Following the 9
26 * WORDs of the METAHEADER there are a further 3 WORDs of 0, 1 of 0x117, 1
27 * more 0, then 2 which may be a time stamp of the file and then the path of
28 * the file (METAHEADERDISK). I've copied this for 16bit compatibility.
