Dragging causes a framerate dip

[adam-savard]

Just flagging this as an issue for anyone else that runs across it!

The framerate will take a massive nosedive if you have dozens of text inputs on screen and you're dragging them inside a container; this is because of the bounds calculation that happens in the _update. There's probably a more efficient way to make this happen, though I don't have any suggestions at this time.

Good point. This could be optimized by not updating the HTML text input internally when the PIXI surrogate is being drawn instead. Of course, if substituteText = false, then this does not apply.
