* Some old struct Preferences fields are now ignored by SetPrefs() (for
    example FontHeight). SetPrefs() also stops listening to the pointer
    fields as soon as a new-style pointer is passed to Intuition
    (new-style pointers can be taller or deeper).

  * Preferences ViewX/YOffset only applies to the default mode. You
    cannot use these fields to move the position of all modes.

  * The Preferences LaceWB bit is not necessarily correct when Workbench
    is in a new display mode (akin to GetScreenData()).
