==========================================================================================================================================

A :ref:`RealPoint`  is a useful data structure for graphics operations.          

It contains floating point `x`  and `y`  members. See :ref:`Point`  for an integer version. 

Note that the coordinates stored inside a :ref:`RealPoint`  object may be negative and that :ref:`RealPoint`  functions do not perform any check against negative values.
