This is pretty much the same for ShadowPrimitive2D as the change for GlowPrimitive2D and SoftEdgePrimitive2D, so for more comments please refer to those commits:c2d1458723707b0c328aThere are some needed differences due to ShadowPrimitive2D having existed longer and is used for non-blurred shadow for a long time and is used as unchanged as possible. Only for active glow of shadow is a buffering and local decompose used.
