rulers: fix subtle off-by-one pixel error caused by double-rounding
...
This change also makes it more clear that we're computing window-coordinate system values
for the x-axis than the previous inaccurate version was

Fix canvas rectangle bounding box
...
When drawing the outline of a rectangle, the bounding
box must cover the whole pixel of the line. Otherwise
the line would be left behind when the rectangle shrinks.

switch from boost::{shared,weak}_ptr to std::{shared,weak}_ptr

This is mostly a simple lexical search+replace but the absence of operator< for

Canvas: allow to group rendering of child items
...
> This group functionality can be convenient for performing
> intermediate compositing. One common use of a group is to

> occlude each other), and then blend the result with
> translucence onto the destination.

The main use case where will be to render opaque layered
[MIDI] regions transparently onto a grid.
