/*
The following example demonstrates the WindowLeft, WindowTop, WindowWidth, WindowHeight, BufferWidth, BufferHeight and CursorVisible properties and the
SetWindowPosition, SetBufferSize and ReadKey methods. The example draws a grid pattern in the screen buffer based on the width of the screen buffer. The example
then moves the console window accordingly when the four console keys, up, down, left, or right, are pressed. Grid mode helps to see the movement of the console window relative to the screen buffer.
