`WebGLPipeline.forceZero` is a new property that informs Game Objects if the pipeline requires a zero bound texture unit.
* `WebGLPipeline.setAttribPointers` is a new method that will set the vertex attribute pointers for the pipeline.
* The pipeline now works with Game Objects that do not have a normal map. They will be rendered using the new default normal map, which allows for a flat light effect to pass over them and merge with their diffuse map colors.
* `Light.dirty` is a new property that controls if the light is dirty, or not, and needs its uniforms updating.
* `Light` has been recoded so that all of its properties are now setters that activate its `dirty` flag.
* The pipeline will no longer look-up and set all of the light uniforms unless the `Light` is dirty.
* The pipeline will no longer reset all of the lights unless the quantity of lights has changed.
* `WebGLPipeline.boot` will now check all of the attributes and store the pointer location within the attribute entry.
* `WebGLPipeline.bind` no longer looks-up and enables every attribute, every frame. Instead it uses the cached pointer location stored in the attribute entry, cutting down on redundant WebGL operations.
* The `ForwardDiffuseLightPipeline.defaultNormalMap` property has been removed as it's no longer required.
* The `ForwardDiffuseLightPipeline.boot` method has been removed as it's no longer required.
* The `ForwardDiffuseLightPipeline.onBind` method has been removed as it's no longer required.
* The `ForwardDiffuseLightPipeline.setNormalMap` method has been removed as it's no longer required.
* The `ForwardDiffuseLightPipeline.bind` is a new method that handles setting-up the shader uniforms.
* The `ForwardDiffuseLightPipeline.batchTexture` method has been rewritten to use the Texture Tint Pipeline function instead.
* The `ForwardDiffuseLightPipeline.batchSprite` method has been rewritten to use the Texture Tint Pipeline function instead.
* `WebGLRenderer.normalTexture` is a new property that holds the currently bound normal map (texture unit one).
* `WebGLRenderer.setNormalMap` is a new method that sets the current normal map texture.
* `WebGLRenderer.clearNormalMap` is a new method that clears the current normal map texture.
* `WebGLRenderer.resetTextures` is a new method that flushes the pipeline, resets all textures back to the temporary ones and resets the active texture counter.
