scale missed from Sprite:get(param)

  @alexzheng there are scaleX and scaleY.
  You can't really use scale for consistency, because those both values may be different, and for consistency you can only set one value and get one value, not two values

  Since there are Sprite:getScale() and Sprite:set('scale', value), there is no reason this param is missed from get, it must be a mistake.

  Well as I said I don't think it is a mistake, because it would have to return two parameters instead of one.
  If on Lua part it would not do much harm, maybe it has something to do with C part implementation.
  Or for example it would mess up the tweening. If you would use scale parameter to tween it would only use the first value ignoring the second.
  And another one, for example using GiderosCodingEasy, it heavily relies on overwriting set/get methods and if there would be the cases, where two parameters returned instead of one, overriding it will get even more complicated.
  
  So is there any specific reason you need this for? as in why you can't use getScale or get("scaleX") and get("scaleY")?

  @ar2rsawseen, you are correct in the fact that when using tweening, it is recommended to set both the scale axis' separately rather than as just one.
  
  But was this topic about tweening or about sprite:get('scale') or a simple sprite:getScale()

  I have no special need for it, I just can not understand why cannot tween scale instead of both for scaleX and scaleY with the same value.

  Yes you could if the value is the same.
  But it is possible to scale x axis on one value, for example 0.75, and scale y acis on another value - 0.5.
  Then the values are different, and you would need to create a special case to handle those kind of situations.
