[Laszlo-user] Setting the parent of a tag

[P T Withington]

`placement` allows you to cause a tag to be laid out in a different  
location in the view hierarchy than its lexical declaration.  The  
names `parent` and `immediateparent` are pretty bad -- they should be  
something like `lexicalParent` and `dynamicParent` or `layoutParent`,  
instead.

Defining your own tag (class) allows you to write constraints easily,  
without having to resort to the underlying `applyConstraint`  
machinery.  It is straightforward to convert a view heirarchy to a  
class, and I recommend this as a way to write constraints for tags  
that you want to dynamically instantiate (over trying to write  
constraints in Javascript).

I'd need to see more of what you are really trying to do to comment  
more intelligently.

You can 'get the benefit of constraints' by writing a class and then  
instantiating the class.
