and create a new CImageButton.
* NxWM::CStartWindow: Now ignores any close application button presses
(You can't close the start window).
* NxWM::CCalibration: The calibration application now has its own thread.
This was necessary for a proper integration with the taskbar.
* NxWM::CCalibration and NxWM:CTouchscreen: Changed the mechanism use
to report calbration data. It is now reported directly from CCalibration
to CTouchscreen. If external logic needs calibration, it can now get it
from CTouchscreen instead of CCalibration. This change was necessary
to make the termination conditions of CCalibration clean (it used to
have to persist until some external logic got the Calibration data).
* IApplication, IApplicationWindow, and all classes that inherit from
these: Now support method to report if the application is a full-screen
or a normal application. This is necessary to prevent CTaskbar from
displaying a task bar on top of a full-screen window.
