The `Multi Pipeline`, `Bitmap Text`, `Render Texture`, `Text`, `TileSprite` and `Camera` now all read the tint values from the public properties instead of the private `_tintTL` etc ones. They also now set the `tintEffect` value directly from the `tintFill` property, removing another conditional check.
* The `Single.frag`, `Light.frag` and `Multi.frag` shaders have all been updated so they now read the color value as `outTint.bgr` instead of `outTint.rgb`. This allows the colors to remain in RGB order within the Tint component.
* The `Single.frag`, `Light.frag` and `Multi.frag` shaders have all been updated so they no longer have a 3-way check on the `outTintEffect` value.
The `WebGLRenderer.rebindPipeline` method has been changed slightly. Previously, you had to specify the `pipelineInstance`, but this is now optional. If you don't, it will use the new `previousPipeline` property instead. If not set, or none given, it will now return without throwing gl errors as well.
`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.
* 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.
* `WebGLRenderer.setTextureZero` is a new method that activates texture zero and binds the given texture to it. Useful for fbo backed game objects.
* `WebGLRenderer.clearTextureZero` is a new method that clears the texture tha was bound to unit zero.
* `WebGLRenderer.textureZero` is a new property that holds the currently bound unit zero texture.
* The property `WebGLRenderer.currentActiveTextureUnit` has been renamed to `currentActiveTexture`.
* `WebGLRenderer.startActiveTexture` is a new read-only property contains the current starting active texture unit.
* `WebGLRenderer.maxTextures` is a new read-only property that contains the maximum number of texture units WebGL can use.
* `WebGLRenderer.textureIndexes` is a new read-only array that contains all of the available WebGL texture units.
* `WebGLRenderer.tempTextures` is a new read-only array that contains temporary WebGL textures.
* The `WebGLRenderer.currentTextures` property has been removed, as it's no longer used.
* `WebGLRenderer.currentTextures` has been removed, as it's no longer used internally.
* `WebGLRenderer.setBlankTexture` no longer has a `force` parameter, as it's set by default.
* `WebGLRenderer.setTextureSource` is a new method, used by pipelines and Game Objects, that will assign a texture unit to the given Texture Source.
* The `WebGLRenderer.setTexture2D` method has been updated to use the new texture unit assignment. It no longer takes the `textureUnit` or `flush` parameters and these have been removed from its method signature.
* The Texture Tint vertex and fragment shaders have been updated to support the `inTexId` float attribute and dynamic generation.
* The Texture Tint Pipeline has a new attribute, `inTexId` which is a `gl.FLOAT`.
* `TextureTintPipeline.bind` is a new method that sets the `uMainSampler` uniform.
* The `TextureTintPipeline.requireTextureBatch` method has been removed, as it's no longer required.
* The `TextureTintPipeline.pushBatch` method has been removed, as it's no longer required.
* The `TextureTintPipeline.maxQuads` property has been removed, as it's no longer required.
* The `TextureTintPipeline.batches` property has been removed, as it's no longer required.
* `TextureTintPipeline.flush` has been rewritten to support multi-textures.
* `TextureTintPipeline.flush` no longer creates a sub-array if the batch is full, but instead uses `bufferData` for speed.
* `TextureTintPipeline.currentUnit` is a new property that holds the most recently assigned texture unit. Treat as read-only.
