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.

use window-based coordinates when picking current item so that we get per-item (per-scroll-group,really) computation of position and coverage.

initial redesign of canvas scrolling to facilitate independent x- and y-axis scrolling of specific groups within the canvas.
...
This commit should cause no change in behaviour, but contains all the code and changes necessary
for the next step

slight code tidy for Line::render() ... don't use 0.5 pixel adjustment if the line width > 1.0

drop use of bounding box to determine whether an item covers a point; add Item::covers(Duple const&)
...
Default implementation for Item still uses bounding box, but specializations for Arc (Circle), Polygon, Line and PolyLine have been added

an awful lot of tweaks to drawing details

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

expand bbox for Canvas::Line to get rid of artifacts caused when moving them around, as is done for Rectangle and others

various work waveview amplitude mgmt; fix playhead cursor drag from timebar click

fix clamping of line and rect coordinates to avoid issues with cairo when drawing way outside a surface's dimensions; move various coordinate methods down to Canvas, because they don't require GTK information; make visible_area() a Canvas virtual method so that we don't have to cast to call it

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
