//*****************************************************************************
//
// This driver operates in four different screen orientations. They are:
//
// * Portrait - The screen is taller than it is wide, and the flex connector is
// on the left of the display. This is selected by defining
// PORTRAIT.
//
// * Landscape - The screen is wider than it is tall, and the flex connector is
// on the bottom of the display. This is selected by defining
// LANDSCAPE.
//
// * Portrait flip - The screen is taller than it is wide, and the flex
// connector is on the right of the display. This is
// selected by defining PORTRAIT_FLIP.
//
// * Landscape flip - The screen is wider than it is tall, and the flex
// connector is on the top of the display. This is
// selected by defining LANDSCAPE_FLIP.
//
// These can also be imagined in terms of screen rotation; if portrait mode is
// 0 degrees of screen rotation, landscape is 90 degrees of counter-clockwise
// rotation, portrait flip is 180 degrees of rotation, and landscape flip is
// 270 degress of counter-clockwise rotation.
//
// If no screen orientation is selected, "landscape flip" mode will be used.
