/** \file main.cpp
 *  \brief mbed Hello World demo for TFT-320QVT module with SSD1289 and XPT2046 touchscreen.
 *   
 *  \copyright GNU Public License, v2. or later
 *  Creates a window, which can be dragged within the screen, and can be closed
 *  with the standard WIndows-style "x"-button.
 *  Window appearance: initial position, size and colors can be changed via defines
 *  Window in this demo can not be moved beyond the screen area except of the right side.
 *  May require a touchscreen calibration procedure using UTouchCD.h
