// Created : 26th August 1996
// By : P.R.Porter
//
// Version Date By Description
// ------- --------- --- -----------------------------------------------
// 1.0 16-Sep-96 PRP Interface to the current scroll position.
//
// 1.1 23-Oct-96 PRP Added definition of _parallaxLine structure.
//
// 1.2 05-Nov-96 PRP Added definition of myScreenBuffer.
//
// 1.3 06-Nov-96 PRP Fixed definition of myScreenBuffer.
//
// 1.4 15-Nov-96 PRP Definition of menubar size removed, and put
// into menu.h
//
// 1.5 24-Jan-97 PRP Added references to parallaxScrollx and
// parallaxScrolly. These are used by the sprite
// drawing code to link sprites to parallax
// layers.
//
// 1.6 19-Mar-97 PRP Added profiling flag for testing purposes.
//
// 1.7 24-Mar-97 PRP Turned profiling off
//
// 1.8 08-Apr-97 JEL Made locationWide and locationDeep accessible
// to other drivers.
