don't add transforms in shape_element() if not necessary

[kjyv]

shape_element() always rotates and translates even if both parameters are 0. This degrades performance for animations.

Ok, but can you also separate the cases where only translation or only rotation are 0 ?

result = Element(new_draw)
if angle:
   result = result.rotate(angle)
if xy != (0, 0):
  result = result.translate(xy)
return result

Sure
