2189 * In WinNT, the DC's world transform is updated as the EMF changes
2190 * the Window/Viewport Extent and Origin or it's world transform.
2191 * The actual Window/Viewport Extent and Origin are left untouched.

2193 * In Win9x, the DC is left untouched, and PlayEnhMetaFileRecord
2194 * updates the scaling itself but only just before a record that
2195 * writes anything to the DC.
2196 *
2197 * I'm not sure where the data (enum_emh_data) is stored in either
