6cc673f0a6 in Canvas::window_to_canvas(), if either x or y coordinate is less than zero, search for the scroll group on the relevant edge.

437099fff9 completely rethink waveform rendering (again)
There are 3 possible components to draw at each x-axis position: the waveform "line", the zero line and an outline/clip indicator.
We have to decide which of the 3 to draw at each position, pixel by pixel. This makes the rendering less efficient but it is
the only way I can see to do this correctly.

590882f3c8 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.

7a05dde39d Use a dumb cache for waveview ImageSurfaces. This halves the size of the
previous one, but usually ends up using three of them at the current
CACHE_HIGH_WATER setting.
Should result in a smaller memory footprint for sessions with
multiple copies of nearby audio segments (electronic style).
The downside is the larger memory footprint for linear recording
sessions if CACHE_HIGH_WATER > 1 (1 giving a max of two
half - sized cache entries per audio stream).

6019f06bdf 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.

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.

2691209050 When removing an item which is event-insensitive, there is no need to repick the current item, since it can never have been used as the current item.

84f55440a3 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).
