React/interpret new SlideBackgroundFill mode for SdrObjects/
XShapes, defined by drawing::FillStyle_NONE and usage of
XFillUseSlideBackgroundItem as (true).
Do so by adding a detection, a mode to SdrFillAttribute,
reacting on it by creating a new implemented B2DPrimitive:
SlideBackgroundFillPrimitive2D provides a Primitive2D for
the SlideBackgroundFill mode. It is capable of expressing
that state of fill and it's decomposition implements all
needed preparation/creation/collecting of the geometry
in an isolated and controllable space and way - the
B2DPrimitive way. It does so based on the given
ViewInformation2D, reacing out for all needed data/
geometry from this.
It clips & transforms/combines as needed, providing the
necessary visualization of the MasterPage content *over*
other objects on the Page/Slide. It is currently simple
buffered (due to being derived from
BufferedDecompositionPrimitive2D) and detects if
MasterPage changes. Still, more may be needed.
