Can we?  SURE!  We did it this way because that's how it worked best for
GTK.  If someone wants to add the handleneeded procedure in TCONTROL and do
the creation there, that would be fine.  We just have to make sure that we
are using the "parent" property then and having the user set it (Lazarus
will set it eventually).  Then when the parent is set, I assume that
HANDLENEEDED is called if no handle exists....

Anyone want to implement this?  You will have to move any CREATECOMPONENT
calls out of the specific components into the handleneeded.....

It seems like (to pick an example) TLabel makes it's GTK object in the
contructor.  This is a bit early.

Can't we delay gtk-creation until HandleNeeded is called?  Its the Delphi
way.
In fact can't we do it in the CreateWindow function?

Am I being too fussy spotting windows divergances here? - but this one is
important to me.
