[Bug 4298] Potential metafile NULL-pointer dereference

If someone were to call gdi32.dll's Escape function, purposely passing a NULL
pointer as the last argument for GETPHYSPAGESIZE, GETPRINTINGOFFSET, or
GETSCALINGFACTOR, it could cause a NULL dereference. However, the problem with
the metafile parsing doing it seems to be fixed.
