GetCharacterPlacementW() fix

[Phil Krylov <phil@xxxxxxxxxxxxxxxx>]

Hello,

ChangeLog:

Phil Krylov <phil@xxxxxxxxxxxxxxxx>
    Added support for returning caret positions from
    GetCharacterPlacementW(). I'm not sure if this will work
    for complex scripts, but still it is better than nothing.
