The library assists design of high-quality industrial control widgets 
for Ada applications. The software is based on GtkAda, Ada bindings to 
GTK+ and cairo. The key features of the library:

  - Widgets composed of transparent layers drawn by cairo;
  - Fully scalable graphics;
  - Support of time controlled refresh policy for real-time and 
heavy-duty applications;
  - Caching graphical operations;
  - Stream I/O support for serialization and deserialization;
  - Ready-to-use gauge, meter, oscilloscope widgets;
  - Editor widget for WYSIWYG design of complex dashboards.

  - The package Gtk.Layered.SVG layer was added to show an SVG image;
  - The package Gkt.Layered.Disk_Needle was added, a needle type used in

  - The package Gtk.Valve.Round_90 example added, it provides a valve 
position indicator;
  - Bordered layers have "lens" with light reflex and shadow;
  - Another bug fix in Gtk.Layered.Editor to work around GNAT compiler 
issues;
