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.

[P4/git history rebuild] odd commit probably caused by a missing Ardour commit. Probably needs reverting in a future global merge

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.

use a centripetal catmull-rom curve to smooth ArdourCanvas::Curve
...
See http://en.wikipedia.org/wiki/Centripetal_Catmull-Rom to understand the benefits of this.

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

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
