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

add some comments to Canvas::Image and ensure that the canvas redraws after a put_image() call is handled in the GUI thread

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

add new canvas Image item, with somewhat optimized API for asynchronous, threaded rendering directly into an image buffer suitable for use by cairo as a source surface (currently untested)
