Merge pull request #360 from insidiator/ticket-356

updated examples
[#356] fixed the defer function call in all examples
changed callback to be passed to play
Allowed some of the function to be chainable
[#303] added a optional `me.Rect` parameter to the `getBounds()` function

that prevent from systematically creating a new object in function
