Rather than make all the BasePrimitive2D classes bear the cost of being an UNO object, we just wrap the top level BasePrimitive2D in this class when we need to pass them over UNO. This reduces the locking overhead when doing normal drawinglayer operations, and reduces the size of drawinglayer objects and the cost of initialising them, which shaves 5% off the load/display time of a large barchart. Add new drawinglayer::convertPrimitive2DContainerToBitmapEx utility method to avoid needing to convert to Sequence<XPrimitive2D> Change-Id: I553eaa4c16ba016b098cb21f6c55f5008f0d9b53 Reviewed-on: https://gerrit.libreoffice.org/c/core/+/126487 Tested-by: Noel Grandin <noel.grandin@collabora.co.uk> Reviewed-by: Noel Grandin <noel.grandin@collabora.co.uk>
