canvas: manually remove changes from 6f91dc0799 and implement same goal in a different way
...
The AudioClipEditor features a scroll bar that is a part of the canvas. Because scroll
groups are at the top level of a canvas, the scroll bar is necessary within a scroll
group, which causes it to get confused about the difference between its own
position within the canvas and that of the scroll group. This commit introduces
a per-Item flag, _scroll_translation, which is true by default. If false, the
item will not have coordinates translated to reflect scroll group position.

canvas: don't call ::size_allocate() for children unless there is just one child and it is "layout sensitive
...
the dumb/Item version of ::size_allocate_children() doesn't do anything but give its full allocation to children, and if there
was more than one child, this could not be done in a "dumb" way. Likewise, if the sole child is not layout sensitive, it
doesn't care about size allocation

Canvas: propagate ::size_allocate() down the item tree
...
This previously wasn't done because of fear that it would affect the traditional fixed-sized canvas,
but only items that _layout_sensitive (i.e. are packed into a constraint packer directly) will
actually do anything in ::size_allocate().
Possibly might want to relax this to cover items that have a constraint packer between them
and a root group.

add a very (very) basic resize/layout design to the canvas
...
Items call ::queue_resize(), which sets a flag in the canvas; at next idle, we call
Canvas::layout() which walks the item tree and recursively calls layout (depth first)
on all items needing a resize.
Only Container types implement layout, and so far only Box
