Shefki:
    Must use IsVisible to skip over hidden frames since inactive frames from
    other profiles in group headers will still be shown but not visible
    because their parent group header is hidden.
    And a function leaked into the global namespace.
    And another global variable leak.
    Another global variable leak.
    Fix a global variable leak.
    Fix some positioning related issues where groups would move from where
    they were positionined in config mode when players actually entered
    the group.
    Prevent groups from being stuck to the mouse while moving in some rare
    cases.
    Ticket 459: Group frame positioning buginess after changing size of a
    layout.
    Fix for frames getting stuck to the mouse while moving.
    Get rid of the ugly gap in the background of the CastBar when the icon
    is shown and it's not set to auto-hide.  In the process end up
    simplifying some of the bar text layout code.
    Add range check for offensive Shaman abilities.
    Make the RangeFader know about resurrection spells and use them to range
    check dead units.
    Hide/Show the minimap icon when the proflie changes accordingly.
    LibDBIcon:Refresh() does not do this for us. :(
    Fix config dialog ghosting of some settings when changing profiles.
    Fix the default texts to not adding a + to the delay for channeled spells
    since they are actually removing time from the channel.
    If the first return for LuaTexts is nil set an empty text.  Allows some
    tags to be simplified such as:
    return Classification(unit)
    is now valid.
    Hmm ok guess we have to actually force the update if we're in config
    mode.
    Fix some weirdness in config mode where force shown frames would get
    stuck when losing their targets.
    Fix a typo
    Speedup for target of and target of target of frames.  Don't wait for
    the timer to catch these frames and fore an update if their parent
    frames updated.
    Fix VisualHeal for cross realm players in BGs.
    Fix cast texts when changing targets mid cast.
    3.2.0 compatability for LuaTexts.
    Have to force DogTagTexts to update if the unit on a frame changes (e.g.
    the vehicle swaps).
    Fix Ticket 461, Wacky Unit Cast Text.
    HideBlizzard needs to update what is hidden when the profile is changed
    since the settings may very from profile to profile.
