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

overwrite state of libs/canvas with code from corresponding period in ardour-cairocanvas
...
This makes continued merges with ardour codebase easier, at the
small cost of removing the XML-based constructors. They were not
in use anyway and their use doesn't really fit into the
conception of the canvas as a dynamic UI element. Could reintroduce
them at a later date.

only queue an item redraw from Item::show() or Item::Hide() if the call changes the visibility status of the item (i.e. make no-ops really be no-ops)

drop use of bounding box to determine whether an item covers a point; add Item::covers(Duple const&)
...
Default implementation for Item still uses bounding box, but specializations for Arc (Circle), Polygon, Line and PolyLine have been added

basically operational switch to canvas drawing coordinates, although text and waves don't work, and redraw areas are too small

fix clamping of line and rect coordinates to avoid issues with cairo when drawing way outside a surface's dimensions; move various coordinate methods down to Canvas, because they don't require GTK information; make visible_area() a Canvas virtual method so that we don't have to cast to call it

virtual Fill:: and Outline:: methods so that Canvas::Items that cache image renderings of themselves can invalidate those caches when colors etc. change; add Item::{begin,end}_visual_change() so that we can notify the canvas more efficiently when *only* visual properties have changed and not the bounding box (probably needs to be used more widely)

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
