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.

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.
