Control
Deprecated
Glok doesn't have skins, so there's currently little point in having a Control class.
In JavaFX, Controls have 3 attributes which make them different from other nodes.
A Skin, which can be switched out for a different one.
Tooltips.
A context menu.
I'm not sure if changing skin is worth it. Lots of people style controls to make them look different, but I've never seen an alternate skin being used. I do like the very clear separation of the front-facing API within the Control and all the private bits in the Skin though.
The other two aren't a big deal, and in fact can be achieved without subclassing Control.
TODO So the question is, do I want Skins, and if not, is there a point in having a Control class? I'm not going to use it for now.
