Draws the contents of a render node on a cairo context.
Retrieves the boundaries of the node.
Returns the type of the render node.
Gets an opaque rectangle inside the node that GTK can determine to
be fully opaque.
Acquires a reference on the given GskRenderNode.
Serializes the node for later deserialization via
gsk_render_node_deserialize(). No guarantees are made about the format
used other than that the same version of GTK will be able to deserialize
the result of a call to gsk_render_node_serialize() and
gsk_render_node_deserialize() will correctly reject files it cannot open
that were created with previous versions of GTK.
Releases a reference on the given GskRenderNode.
This function is equivalent to calling gsk_render_node_serialize()
followed by g_file_set_contents().
