[issues 1479: lottie](#1479) - optimaze stroking algorithm by prevent vector normalizations - using render meshes heaps to reduce webgpu instances re-creations - using single instance of pilylines for standard operations such as trim and split - "on-the-fly" strokes generations with dash pattern - "on-the-fly" mesh objects generation in a process of path decoding - merge strokes into single mesh by each shape
