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 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.
* 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.
* 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.
