[bbazukun123]

v8 Upgrade Journey

• Upgrade to the latest pixi v8 and all the supported plugins' version. Currently linking locally these dependencies:
  • @pixi/ui - v8 branch
  • @pixi/sound - feature/v8 branch
  • @pixi/spine-pixi (pixi-spine-v8 repo) - repo-move-prep branch
• Update application init syntax.
• Update application's view reference to canvas , eg. document.body.appendChild(app.canvas).
• Update Ticker callback functions' parameter to be of type Ticker instead of number.
• Replace all Sprite.from(Texture.WHITE) with new Sprite(Texture.WHITE).
• Replace all updateTransform overrides with this.onRender = () => this.renderUpdate() where renderUpdate is a custom function.
• Remove canvas parameter from Label class which extends the Text class.
• Rename label variable on UI elements which overlap with Container's label, ie. in this project -> messageLabel.
• Update pixi UI's slider function override from on onUpdate to onValueUpdate.

Known Issues

• Type Error when doing x.filters = null.
