Camera follow game object before Game's 'prerender' event

[rexrainbow]

I try to draw game objects on render texture, with the related position of game window. It works fine if camera dose not follow a game object (startFollow). I can't get camera's final scrollX, scroll if camera follows game object.
Camera follows game object in game.scene.render, there is no event I can use to get the result of camera scrolling.
My workaround is replacing built-in camera following by setting camera scrolling manually under 'prerender' event.

See the new FOLLOW_UPDATE_EVENT to deal with this situation.
