    app: layers-text-tool should give the focus to the canvas.
    
    If focus is on the layer list for instance, running this action from
    right-click menu raises the on-canvas toolbar, ready for edition, with a
    visible text cursor. But if the canvas has no focus (since you clicked
    on the layer list, it has the focus), you still have to move your mouse
    over and click the text on canvas. That doesn't make sense and there
    would be barely any reason to use this over selecting the text tool then
    clicking the canvas.
