   ===========
   As the name of the file suggests, a couple of miscellaneous 
   functions are grouped in this file.

// Functions:
//    MIN(a, b)
//       Returns the minimum of the two parameters
//    MAX(a, b)
//       Returns the maximum of the two parameters
//    float d_to_l(int DeviceCoord)
//       Returns the logical equalent of the device coordinate passed as
//       a parameter
//       -- The parameter specifies a device coordinate
//    int l_to_d(float LogicalCoord)
//       Returns the device equalent of the logical coordinate passed as
//       a parameter
//       -- The parameter specifies a logical coordinate
//    Position d_to_l(const GraphicPosition &DeviceLocation)
//       Returns the logical position equivalent to the device position
//       passed as a parameter 
//       -- The parameter specifies a device position.
//    GraphicPosition l_to_d(const Position &LogicaLocation)
//       Returns the device position equivalent to the logical position
//       passed as a parameter 
//       -- The parameter specifies a logical position.
