New backstage events

It's to bad that Form_Activate doesn't fire unless the user clicks on something on the form - I think the Codejock code should activate the form, so that it fires.

Form_Paint does fire every time, but unfortunately it also fires when the form is moved and new portions of the window become visible.  I though of using a flag to test just for the first time it fires, but then we'd need to reset when the form becomes invisible and the Deactivate event only fires when the user clicks on another form in another backstage tab (not when the form becomes invisible).

You might be able to subclass the form to check for Visibility changes, but this is a pain for something that the CJ control could provide relatively easily.

Thanks.

To Show Backstage call

And for when a Backstage Tab is clicked\opened we added:

Private Sub CommandBars_ControlNotify(ByVal Control As XtremeCommandBars.ICommandBarControl, ByVal Code As Long, ByVal NotifyData As Variant, Handled As Variant)
    If (Code = XTP_BS_TABCHANGED) Then
        Debug.Print Control.Caption
    End If
End Sub

Thank you for adding these upcoming enhancements to the BackStageView feature.
But I have found a glaring issue that I can't seem to resolve and wondering if you could help.

I am using a form with controls aligned along the bottom of the form and when the form is displayed in a tab of the BackStateView, it seems as though the resizing of the form insists on cutting off the bottom of the form.  In other words, the form is not aligned to "fill" the client area, but instead its height is set to greater than the client area so a significant portion of the bottom of the form refuses to show.  Perhaps this is due to a miscalculation of the NEW height of the form within the client area container.  Please advise.

HINT: This bug will only be visible if there are controls at the very bottom of the child form being used in a backstage tab.  The sample app does not show this issue due to the fact that the backstage client forms in the sample do not have controls along the bottom.
