int winid = setupGLUT(&argc, argv);
// open a new scope, because the pointers below should go out of scope
// before entering glutMainLoop.
// Otherwise OpenSG will complain about objects being alive after shutdown.

/*
An Attachment is a special field container that can be attached to
many of the internal classes like Nodes, NodeCores and many others.
There can be multiple Attachments attached to an object.
Attachments can be attached to all FieldContainers that are derived from
AttachmentContainer. This includes most higher-level classes in the
system, like Nodes, NodeCores, Windows, Viewports etc. See the
inheritance graph for details.
One predefined kind of Attachment is the Name, which can
keep the name of an object. Some of loaders (e.g. the WRL loader)
create these kinds of Attachments for named nodes.

An Attachment is a FieldContainer and as such needs to be created using
::create().
