[x3d-public] Removal of Layout component in X3D v4

I think a networking component is good, if only for chat or sharing position information in a shared virtual world. I agree that a second application can be used for communication. Position information is more world related, and I think should be integrated with x3d, just as avatars are.
Secondly, I imagine myself using my voice or body movement to create virtual worlds, in an accessible sense.
Holger, don’t forget html5 as an option for x3d v4.
We should also consider the potentially ad hoc nature of a networked virtual world, or serendipity. There at a minimum should be a way of communicating either email address or skype id, in world.

Holger, Michalis et al,
I third both motions.
1) Layout/Layer - I remember thinking there was something a bit strange and fuzzy-thought maybe Scene:Layer and Layout:Layer would make some sense as long as you can route or hyper-route between them, in other words instead of Layer as a node type buried in a scene, it could be a hyperscene of some sort.
So maybe some refactoring. But seemed handy - I like it.
2) DIS - I implemented just so I could cross the FULL finish line for bragging rights, but no one has asked for it, and I keep it disabled in the browser unless specifically turned on by commandline option by user. It doesn't fit well with what we are doing -some military-specific nodes- but other multi-player designs might be interesting perhaps at a hyper-scene level rather than buried in scene nodes.

support both Holger's suggestions :)
1. While we don't implement Layout component *yet* in CGE, it does
seem useful and users are actually asking me to implement it. So
(speaking for users) deprecating Layout does not seem desired.
(The reason why it's not implemented *yet* in CGE is that it
wasn't desperately needed, because in CGE we have a similar feature
covering similar use-case. CGE developer can use several
TCastleSceneManager or TCastleUserInterface Pascal components rendered
on top of each other. This covers similar use-cases as the X3D Layout
component. Although it is not available to X3D author (using only
view3dscene), it's only available to CGE developer designing the UI
using CGE components in Pascal.)
2. I don't think we will ever implement, or need, DIS in
CGE/view3dscene. DIS seems tailored to a specific use-case/application
of a military simulation.
While some terms of DIS (like "ammunition" or "detonations")
occur also in computer games, they would definitely not be expressed
by DIS nodes (because each game has very different needs here) by CGE
users. Thus, we have no chance of ever achieving "Full" profile
compatibility for X3D within CGE -- as "Full" includes DIS.
If DIS is indeed useful to particular military organizations,
perhaps the DIS component could be moved to a separate specification,
and not be part of the "Full" profile? And if it's not used, the
simply deprecating it seems like a reasonable choice. I'm not aware of
any other 3D model format that contains this feature, at least in
