Virtualvfunc_virtual function; called each time a Clutter.Content is detached from a Clutter.Actor.
Virtualvfunc_Retrieves the natural size of the content, if any.
The natural size of a Clutter.Content is defined as the size the content would have regardless of the allocation of the actor that is painting it, for instance the size of an image data.
Virtualvfunc_Invalidates a Clutter.Content.
This function should be called by Clutter.Content implementations when they change the way a the content should be painted regardless of the actor state.
Virtualvfunc_Signals that content's size changed. Attached actors with request mode
set to Clutter.RequestMode.CONTENT_SIZE will have a relayout queued.
Attached actors with other request modes are not redrawn. To redraw them too, use Clutter.Content.invalidate.
Virtualvfunc_virtual function; called each time the content needs to paint itself
Interface for implementing Content. Contains only the virtual methods that need to be implemented.
