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
> render objects as opaque within the group, (so that they
> 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.
