[gtkada] ANN: Ada industrial control widgets v.1.1

[Dmitry A. Kazakov]

The library is provides meant for designing high-quality industrial control
widgets for Ada applications. The software is based on GtkAda and cairoada,
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.

This release introduces waveform layers and multi-channel oscilloscope
widgets for rendering massive amounts of data in real-time, with data
sampled asynchronously to rendering. The oscilloscope widget can be used
for plotting purpose as well. The widget supports graph papers, annotated
axes, auto- and manual scaling, visual zooming, zooming undo/redo buffers,
mouse hovering. All widgets support rendering of snapshots on the surfaces
supported by cairo, e.g. into a PDF or SVG file. The library is fully
compatible to the GtkAda versions 2.14, 2.18 and 2.24. It is packaged for
Debian and Fedora, 32- and 64-bit x86 platforms.
