+ *  \brief mbed Window Dragging 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
+ *
+ *  Made by Dmitry Shtatnov, SSSR Labs
