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.

Curve: anti-aliasing.
...
use cairo for anti-aliasing, and ignore explicit Catmull-Rom
points for that fall on the same x-cordinate.

fix x-fade drawing
...
Catmull-Rom curve samples are not equally spaced on the x-axis.
Furthermore, Curve::map_value() is not needed, cairo line_to
already interpolates.

big rework of scrolling, horizontal part considered almost 100% done.
...
Many more changes than I would typically like in a single commit, but this was all very intertwined.
Vertical scrolling using track-stepping still to follow.
