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

Child items will be hidden when their ancestors are hidden. The old ::visible() implementation didn't reflect this. In addition,
when changes are made to hidden items (new definition of visible/not visible), don't bother to request redraws, since this will
be done when the item becomes visible again.
