[AdgGtkArea] Added support for "render-map" property

A new layer of transformation, applied just before the rendering and
after the global transformation. This allows to align and zoom the
canvas without affecting the global matrix.

Modified the extents concept of an AdgGtkArea instance by adding margins
and by considering the render map.
