1.0 2012-03-22 Gregory Nutt <gnutt@nuttx.org>

* The initial release of the NxWidgets package

1.1 2012-xx-xx Gregory Nutt <gnutt@nuttx.org>

* Updated and verified the NxWidgets DOxygen documentation.  Contributed
  by Jose Pablo Carballo.
* IBitmap, CRlePalettBitmap:  Extended class to support differnt LUTs
  for selected and non-selected images.
* CImage: If selected, uses different LUTs based, different borders.
  CImage is now basically a button type.
* CImage: Add logic to hightlight an CImage (using the selected LUT).
* nxwm: The tiny NX window manager (NxWM) is being developed in this directory.
* UnitTests/nxwm:  A unit test for the NX window manager.
* CWidgetControl:  Add a semaphore to force clients to wait if the
  size or position of the window is not yet known (multi-user mode only).
* During integration of NxWM, corrected numerous problems with NxWidgets
  running on toolbars and framed windows.  That capability was commented
  out in the 1.0 release but is verfied functional in 1.1.
* CRlePalettBitmap: Fix an error in the text that determines if we
  need to "rewind" to the beginning of the image.
* CRlePalettBitmap: Fixe a positioning problem.  It was actually losing
  the last row of every image!
* CNxWidget: Removed support for "shelving" widgets.  I will be removing
  some lesser used feature over time in order to reduce the NxWidgets
  footprint.
* CNxWidget: Removed support for reference constants and close types.
  The goal is to ge the base widget class as small as possible.
* CNxTkWindow:  Fix uninitialized pointer value.
* CNxToolbar:  Need to "fake" the fix position callback to avoid
  deadlock waits for the callback that won't happen.
* CNxTkWindow:  Fix toolbar background color
* CWidgetControl:  Don't declare the the geometry is good until a non-NULL
  window size is received.
* CGraphicsPort and CWidgetControl:  If the underlying graphics device
  is write-only, then we have to render fonts a little differently.
* CNxWidgets, CWidgetControl, and CRectCache:  Big change!  Remove all support
  for widgets in a "vertical" hierarchy.  Now widgets exist in a flat,
  two-dimensional space and should not overlap.  This should greatly
  reduce the memory requirements and, since, NuttX already supports
  a hierarchical windowing system, does not result in loss of functionality.
* CNxWidgets and CWidgetControl.  Remove specific built-in support for
  modal loops.  There are too many different control mechanisms that might
  be needed.  Replace with hooks to control widget events from totally
  external logic.
* CWindowEventHandler, CWindowEventHandlerList, CWidgetControl: New
  callback classes to receive notifications about window events.
* NxWM::CFullScreenWindow and NxWM::CTaskbar:  Add support in NxWM for full
  screen window applications.
* All application windows now use CWindowEventHandler and CWindowEventHandlerList
  to get notifications about mouse and keyboard events.  These class will
  then automatically handle polling (with no need for a modal loop).
* NxWM::CTouchscreen and NxWM::CCalibration: Add touchscreen support (still a long
  way to go).
* NxWM::g_playBitmp: Change the play icon again.  These tiny touch icons
  must be very simple.
* NxWM::CCalibration: Beef up touch input handling logic.  Now changes the
  color of the touch circle to yellow when it is touched.
* NxWM::CTouchscreen: Do not read touchscreen data when there is no consumer.
* NxWM::CWindowControl:  Add new class to wrap CWidgetControl and provide
  some special mouse and keyboard input event handling.
* NxWM::CTaskbar: Correct the calculation of the physical size of the
  display.
* NxWM::CCalibration: run method must clear m_stop when returning, or you can
  never restart the Calibration window.
* NxWM::CTaskbar: On a failure to start an application, the application icon
  CImage was being deleted twice.
* NXWidgets::CImage: Now handles mouse click callbacks.  CImage is now really
  a button.  Probably should separate basic imaging functionality as CImage
  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.
* NxWM::CTaskbar:  Ooops... minimizing the wrong application!
