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

experimental drawing optimization.
Q: is bounding_box(); etc more complex than queuing draw?
either way, canvas should eventually switch to
use an optimized OptimizingLookupTable.

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

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

make PolyLine use distance_to_segment_squared(), and add separate (null, for now) method Curve::covers(Duple) because the math there needs to be different, maybe

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
