c4e31fc322 Add an optional ArdourCanvas::Item::prepare_for_render interface 
Called when an item has requested a redraw and intersects with visible
canvas area.

Also add Canvas::prepare_for_render that will call Item::prepare_for_render for
items visible on the canvas.

4fa4b9a135 remove use of boost::optional to define "undefined" Canvas::Rect, and use Rect::empty instead. 
This commit includes Rect::operator bool() which might be a candidate for removal in a future commit, in an attempt
to make the meaning clearer

6a5d805b38 more canvas refactoring. 
Remove Canvas::Layout, use Canvas::Container for the same purpose, move child-rendering into Item::render_children() so that it
could theoretically be used by any derived type.
