''self.allocation'' property is no longer available and we should use <tt>self.get_allocation_width</tt> to get the allocation size:

self.allocation.height
should be replaced by:
self.get_allocated_width()
self.get_allocated_height()

Rsvg.Handle.new_from_data(data)

<tt>Gdk.Window.invalidate_rect</tt> takes a ''Gdk.Rectangle'' instead a tuple in Gtk3.
rect = Gdk.Rectangle()
rect.x, rect.y, rect.width, rect.height = (0, 0, width, height)
self.get_window().invalidate_rect(rect, True)
