use window-based coordinates when picking current item so that we get per-item (per-scroll-group,really) computation of position and coverage.

various changes to get independent scrolling to work better in canvas. mostly tweaks relating to how scroll offsets are used during rendering.
...
Event handling offsets still require work.

different approach to independent scrolling, involving ArdourCanvas::ScrollGroup
...
The idea now is that a scroll group item can be added to the canvas which will causes its children to scroll in either or both
directions (horizontal or vertical). There are few complications: the position() of the ScrollGroup is ambiguous depending
on whether you want it with scroll taken into account or not, so Item::canvas_position() was added, which defaults to
the same value as Item::position() but is overridden by ScrollGroup to return the position independent of scrolling. This
method is used when translating between item/canvas/window coordinate systems.
Note that the basic idea is that we MOVE the scroll group when a scroll happens. This mirrors what happens in the GnomeCanvas,
where Nick Mainsbridge came up with a great idea that allowed unification of the time bar and track canvases.

initial redesign of canvas scrolling to facilitate independent x- and y-axis scrolling of specific groups within the canvas.

This commit should cause no change in behaviour, but contains all the code and changes necessary
for the next step
