matrix-engine-wgpu/src/shaders/instanced/vertexShadow.instanced.wgsl.js

Networking implemented - based on kurento openvidu server. fix arcball camera,instanced draws added also effect pipeline blend with instancing option.Normalmap added, Fixed shadows casting vs camera/video texture, webGPU powered pwa application. Crazy fas
