Automatic Drawing Generation

The autoscaling feature is now available, and a series of predefined scale factors are applied
until the proper one is found.

The demo program autoscales the drawing on a right-click on the drawing area.

The introspection support has been improved,
making it possible to have LGI (Lua) bindings working out of the box.

The typedef hack has been dropped in favor of a private forwarder header.

The dash pattern of AdgLineStyle can now be customized by binding to it an AdgDash instance.

The text manipulation logic has been moved inside the AdgTextual interface and a new entity based on pango (AdgText) has been added. The demo program has a new dialog page that allows you to customize the title block of the drawing. The CPML library has its own test framework and it is now possible to generate a report by using "make test-report". The missing extents computation on AdgRDim, AdgADim, and AdgArrow are now in place. Running "adg-demo -E" shows the extents status. A bunch of bugs, most notably the wrong glade catalogdir detection and some extents computation, have been resolved.

The localization infrastructure has been added and tested by adding the Italian translation. The AdgGtkArea widget is now capable of interactively changing zoom and pan in global space by dragging and/or rotating the wheel while keeping Shift pressed. A new class has been added: AdgGtkLayout is an AdgGtkArea based widget that implements scrolling natively, hence it can be added directly to a GtkScrolledWindow container.

The canvas now has printing support when compiled with GTK+ enabled. The media setup can be associated to the canvas so this data can be accessed to provide a consistent behavior between different backends.
The demo program can now render the drawing to an SVG file. Generated files are stored in the user document directory. Incomplete entities now fail gracefully instead of complaining for insufficient data. This provides an easy way to implement optional machinings: the optional groove in the adg-demo program is working by leveraging this feature.

The portability of the build system has been improved: the tarball now builds out of the box on FreeBSD, OpenSolaris, MinGW32, and GNU/Linux. The adg-demo program has been rewritten from scratch to provide a nice example of what the ADG should be used for. The rendering has been cleaned up and the model-view interaction now works: changing the data modifies the drawing. The project tree has been rearranged into three different subprojects: CPML (mathematical stuff above Cairo), ADG (the canvas above CPML) and ADG-GTK (user interface helpers above ADG and GTK+). Support for glade has been added.
