docs: <B>For the real size, see {@link #getAttributeSize(ScoreAttribute)}!</B>
  <br>
  Gets the size of an attribute, without calculation i.e. the value
  returned has no unit information, you will not know if it's
  {@link SizeUnit#PX} or {@link SizeUnit#STAFF_HEIGHT} or ... <br>
  <br>
  May be useful for option panels where slider or other input component
  have the rough size value, without unit, and you want to keep the default
  unit (using {@link #setAttributeSize(ScoreAttribute, float)})
  
  @return a float value
  @throws AttributeNotDefinedException
  if attribute has not been defined in the template
  @throws RuntimeException
  if attribute doesn't accept size value
