    clutter/paint-nodes: Use texture position to draw pango layout
    
    When painting a ClutterText, there are two different aspects that
    should be taken into account:
    
     1. The allocated size of the actor; and
     2. The reported size of the PangoLayout, which may be smaller or
        bigger than (1)
    
    When (2) is bigger than (1), ClutterText has to clip the text to
    only draw at the visible contents over the actor surface. In
    addition to that, ClutterText also tracks the cursor position,
    which makes clipping a bit more complicated.
    
    The current ClutterTextNode.draw() implementation assumes that
    the (1) also represents (2), which is not true. This makes
    clipping not work.
    
    Fix that by assuming that the position to draw the PangoLayout
    is passed as the second rectangle, and the actor size is the
    first one.
