 * RetroFont has been updated to use RenderTexture.renderXY, removing the need for creating a Point object each update.
 * RetroFont no longer puts any entries into the TextureCache or generates any UUIDs on instantiation, speeding up creation and lowering memory use.
 * BitmapData.update now validates the `width` and `height` values to ensure they aren't lower than 1, which would previously cause a context error.
+* Texture.requiresReTint is a new property that controls if a texture requires the display object to be re-tinted having been updated internally. The LoadTexture component now sets this.
+* PIXI.Sprite.tintedTexture contains a canvas object that holds the tinted version of the Sprite. This is only populated in Canvas, not in WebGL.
 
 ### Bug Fixes

 * Fixed a bug in Pixi where drawing a Sprite to a RenderTexture would reset the Sprites transform to an identity Matrix.
 * The SoundManager didn't accurately detect devices or browser environments with no sound card present and would try to carry on using a null Web Audio context (thanks @englercj #1746)
 * The Tween.onStart signal wasn't dispatched if the Tween had a delay set. It's now dispatched immediately if no delay, or after the delay if set. It also respects the `autoStart` parameter and will still dispatch even if `autoStart` is true.
-* PIXI.CanvasTinter.tintWithMultiply was performing a double drawImage operation for no reason. Simplified down to a single drawImage call.
 * Input.addMoveCallback used to return the index of the callback entry in the internal `moveCallbacks` array. However as callbacks were removed the indexes became invalid, potentially causing a future `Input.deleteMoveCallback` to remove the wrong callback entirely or error. Input.deleteMoveCallback now takes the original callback and context as its parameters to ensure deletion safety.
