Georges Basile Stavracas Neto 0f0b411f6e clutter/content: Add clutter_content_invalidate_size()
ClutterContent has the ability to dictate the layout of any
given actor, through the CLUTTER_REQUEST_CONTENT_SIZE request
mode.

However, there is no way for ClutterContent implementations
to notify their attached actors that the content size changed.

Add a new optional ClutterContent.invalidate_size() vfunc and
clutter_content_invalidate_size().
