Blink action usage was confusing. (#279)
Couldn’t use the width and height properties of a Texture after it loaded. (#355)
Using on(‘pointerdown’) would not automatically enable pointer capturing. (#398)
Unsubscribing from an event sometimes removed other event handlers. (#366)
Actor.setCenterDrawing() was hard-coded to true. (#375)
