Suggestion: Add children param to Group constructor

Is your feature request related to a problem? Please describe.

When using Group we always end up using the same pattern:

//create group
let group = new Group();

//create meshes
let m1 = new Mesh( geom, mat );
let m2 = new Mesh( geom, mat );
...

//add meshes
group.add( m1 );
group.add( m2 );
...

return group;

I think this can be simplified if Group accepted children as parameter in constructor, as Mesh accepts Geometry and Material.

Describe the solution you’d like

Using the proposed change the code would look like:

//create meshes
let m1 = new Mesh( geom, mat );
let m2 = new Mesh( geom, mat );

return new Group( [ m1, m2, ... ] );

I think Group should accept children as parameter since its purpose is precisely that, having children. And it would simplify the code.

If we do this, users could expect we change the constructor of Bone in the same fashion. Simply because in many cases bones do have bones as children.

I think it’s better if 3D objects only accept a geometry and/or material parameter. And that’s it.

Are you aware that you can do this?

group.add( m1, m2 );

This works with an arbitrary number of arguments. Against this backdrop, I do not vote to change the API.
