AdgADim, a new entity to quote angular dimensions, has been implemented. The linear dimensions now accept the "outside" property to reflect the arrows in reference to the extension lines. By default, the value of this property is undefined and will be computed runtime depending on the quote size and the available space. The new AdgEdges model can now be used to programmatically build a serie of vertical lines expressing the edges of another model. This can be used on symmetrical shape, often met in turned parts. The entities now actively responds to extents requests, so it is possible to get the needed space before rendering them. Any matrix change now emits specific signals to fulfill this requirement.
