[debug] fix bouding box drawing for entity renderable component in a …

…nested container

not sure this fix is generic enough to cover all scenarios, but it works for now for all the built-in examples

renderer resize optimization and other related improvements

- cleaned up me.video, by registering the root container on the canvas resize event and updating the child bounds (makes more sense to have that here rather than being called from me.video....)
- rendererer resize now only resize the canvas if the given size is actually different and trigger the coresponding event
- made me.Container.root a public property, and allow to pass as an argument if the container is a root container (cleaning code here and there)
- debugPanel now listen to the canvas onresize event, as opposed to the viewport one

CHANGELOG : missing parenthesis

small test unit improvements

- added a rotate test for me.Line, which also validate the call to the constructor with a list of object (as opposed to a list of Vector)
- fix wrong url for the utils unit when running through a browser
