Curve: anti-aliasing.

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.

Vertical scrolling using track-stepping still to follow.

alter ArdourCanvas::Rect::expand() to not clamp to all-positive values because we now definitely have items that have negative coordinates.

This could have drastic consequences but I think the all-positive was a hack to fix a problem that was solved separately by means currently unknown.

manually revert change to canvas expose handling in fee026c5ef
...
Breaking out the rectangles implies a z-axis ordering of drawing,because the rect drawn last will implicitly be "on top".
But redraw areas are not submitted with any z-axis information, and so drawing like this breaks canvas layering. It
would be more efficient to draw the rects separately, but we don't have any ordering information and so we cannot do it
correctly.

fix redrawing of canvas with an optimized build
...
Best guess right now is that optimization does something bad when ceil() is called twice on a very large dbl-precision number,
which results in a zero (empty) redraw area. Without the removal of the redundant ceil & floor functions, no expose events
would be delivered to the canvas in an optimized build during drags (and maybe more).
