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.

"correct" curve drawing (no artifacts during redraw)
...
Interpolation errors still need addressing.

change implementation of ArdourCanvas::Curve to use GIMP-inspired ideas.
...
Presmooth with quadratic bezier, then interpolate when rendering. Not finished yet

implement Curve::covers() in a very primitive way (also note: fails for actual spline curves)

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
