 * `SpineCanvasPlugin.shutdown` would try to dispose of the `sceneRenderer`, but the property isn't set for Canvas.
 * `ArcadePhysics.Body.checkWorldBounds` would incorrectly report as being on the World bounds if the `blocked.none` flag had been toggled elsewhere in the Body. It now only sets if it toggles a new internal flag (thanks Pablo)
+* `RenderTexture.resize` wouldn't update the CanvasTexture width and height, causing the cal to draw or drawFrame to potentially distort the texture (thanks @yhwh)
