0028654: Existed tool (gendoc) for generation documentation does not take into account size of images.

The parameter defining image width has been added to all figures to improve their layout in PDF documents and tweaked depending on the nature of each image.
Additionally, some minor changes improving image and text layout have been introduced.

Remove temporary added possibility for setting image width automatically for generation of pdf documentation.

 Logically the *TObj* data model is represented as a tree of model objects, with upper-level objects typically being collections of other objects (called *partitions*, represented by the class *TObj_Partition*). The root object of the model is called the *Main partition* and is maintained by the model itself. This partition contains a list of sub-objects called its *children* each sub-object may contain its own children (according to its type), etc.
