QDockWidget behavior is not consistent with the Operating System

In both 4.3 and 4.4....

1) If a docked QDockWidget is dragged to a new location, the dock
area animations ALWAYS display no matter what the OS settings are set
to. The OS is being ignored in this case.

2) If an un-docked QDockWidget is dragged to a dock area the
animations are NOT always displayed. The OS is being obeyed in this case.

Qt needs to be consistent. Either, always follow the OS settings or
let us turn dock animations to on/off/followOS using the Qt API.
