2186 * This function behaves differently in Win9x and WinNT.
2187 *
2188 * In WinNT, the DC's world transform is updated as the EMF changes
2189 * the Window/Viewport Extent and Origin or it's world transform.
2190 * The actual Window/Viewport Extent and Origin are left untouched.

2192 * In Win9x, the DC is left untouched, and PlayEnhMetaFileRecord
2193 * updates the scaling itself but only just before a record that
2194 * writes anything to the DC.
2195 *
2196 * I'm not sure where the data (enum_emh_data) is stored in either
