2019 * NOTES
2020 * This function behaves differently in Win9x and WinNT.
2021 *
2022 * In WinNT, the DC's world transform is updated as the EMF changes
2023 * the Window/Viewport Extent and Origin or it's world transform.
2024 * The actual Window/Viewport Extent and Origin are left untouched.
2025 *
2026 * In Win9x, the DC is left untouched, and PlayEnhMetaFileRecord
2027 * updates the scaling itself but only just before a record that
2028 * writes anything to the DC.
2029 *
2030 * I'm not sure where the data (enum_emh_data) is stored in either
2031 * version. For this implementation, it is stored before the handle
2032 * table, but it could be stored in the DC, in the EMF handle or in
2033 * TLS.
