remove use of boost::optional to define "undefined" Canvas::Rect, and use Rect::empty instead.
...
This commit includes Rect::operator bool() which might be a candidate for removal in a future commit, in an attempt
to make the meaning clearer

refactor Canvas so that all Items have children; add Container abstract base class; rename Group as "Layout" and retain only drawing semantics

change Canvas heirarchy and constructors
...
Items no longer need a parent group (they require a Canvas pointer instead), so all constructors have been rationalized
and have two variants, one with a parent and one with a canvas.
All Items now inherit from Fill and Outline, to banish diagonal inheritance and virtual base classes and all that.
There were zero changes to the Ardour GUI arising from these changes.

basically operational switch to canvas drawing coordinates, although text and waves don't work, and redraw areas are too small

remove all XML related API from canvas. it may have been useful during development, but it is just a distraction - we will NEVER be saving or restoring canvas state via XML or any kind of serialized state
