change Canvas heirarchy and constructors
...
Items no longer need a parent group (they require a Canvas pointer instead), so all constructors have been rationalized
and have two variants, one with a parent and one with a canvas.
All Items now inherit from Fill and Outline, to banish diagonal inheritance and virtual base classes and all that.
There were zero changes to the Ardour GUI arising from these changes.

fix gradient pattern origin translation for time axis view items
...
note: the solution is non-obvious, but the obvious one of applying a translational Cairo::Matrix to the gradient
caused an exception to be thrown because of a non-invertible matrix.

change UIConfig to use accessor/setter methods like RCConfig so that ParameterChanged methods can actually be emitted; add variable (over a small range) background shading for all TimeAxisViewItems

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
