'_wasPreviouslyReady' for ShaderMaterial?

[heyzxz]

Hi there,

According to this: https://github.com/BabylonJS/Babylon.js/blob/master/src/Materials/babylon.shaderMaterial.ts#L163-L217

I think the ShaderMaterial is doing the full 'Ready checking' every frame, and I'm just wondering why didn't use the '_wasPreviouslyReady' flag just like other materials (standard, PBR) did to make it possible to skip the full ready checking ?

if (this.isFrozen) {
    if (this._wasPreviouslyReady) {
        return true;
    }
}
