    Support buffering SystemDependent GraphicData
    
    Started to make the buffering more flexible by adding
    virtual methods
    
            virtual sal_uInt32 getHoldCyclesInSeconds() const;
            virtual sal_Int64 estimateUsageInBytes() const;
    
    to class SystemDependentData. This will allow to add more
    sensitive buffering/caching.
    Also fine-tuned Linux-derived classes actively used for buffering
    to be more sensitive when and where to reuse the buffered data

    Support buffering SystemDependent GraphicData (III)
    
    This change is for speedup of fat line drawing when using
    X11. This is a long-term problem which never really progressed,
    but is avoided using Cairo in the future. Still - if used,
    speedup using current state and buffering possibilities.
    
    Two speedup steps will be used:
    (1) The tesselation is no longer done using trapezoids. That
    works (but was done wrong leaving artifacts) but is not fast
    and done every time. It is even not done with FatLines and
    more than 1000 points.
    New version will use triangulation. Dspite using the existing
    triangulator (that works but is slow) extend the FatLine
    geometry creator to directly create triangles.
    This is also necessary since for buffering that data a
    transformation-invariant version is needed (in device coordinates
    the data changes all the time when scrolling). Trapezoids are
    by definition *not* transformation-invariant (e.g. rotation)
    
    (2) Buffer that triangulation - with the needed care and watch.
    It is e.g. necessary to react on 'hairlines' since these change
    their logical LineWidth view-dependent (zoom). In those cases, the
    buffered data *has* to be removed due to the base for buffering is
    the created FatLine geometry based on one stable logical LineWidth
    
    Also took the time to adapt B2DPolygonTriangulator to use an
    own data type (B2DTriangle) and a vector of these for better
    understandability and security. Adapted all usages as needed.
