commit 5e3eabac0acfb95bb38c68ed15871883760e11c8

    editviewoverlay: EditViewSelection reorganized
    
    The Selection visualization in EditVierw is organized
    to use XOR for visualization, thus DrawSelection is
    used e.g. before and after changes to the Selection.
    Ensured athat all changers of selection have to use
    SetEditSelection by making return of GetEditSelection
    const. This allows to use a central and safe
    SelectionChanged which is needed for alternatives of
    Selection visualization.

    editviewoverlay: Allow EditView to run in Overlay
    
    This is the first basic functionality to get the active
    EditView with EditEngine work in the Overlay which all
    Apps support. Reason is that the current EditEngine 'plugs'
    into the Window and uses Invalidate() calls to repaint
    deeply everything under a text change. While this is
    acceptable for simple cases it can get very slow when
    there are excessive, expensive to paint objects in the
    background, e.g. MasterPages in Draw/Impress with gradients
    and other stuff. This was avoided in older versions (LO51)
    by 'guessing' a good BackgrundColor by the EditEngine,
    not invalidating but painting actively using that guess
    (with better or worse results) which someone removed.
    For the future it is anyways the better way to get the
    EditEngine functionality to Overlay and using Primitives,
    this will be a first step. This may enable Text Editing
    without repainting the Background (fast), using a non-XOR
    selection paint and more. It will need thorough testing
    and further experimenting due to EditEngine being used in
    many places (DrawObjects, Calc Cells, Formular Fields,
    Controls, ...)
