Debugging is not mandatory for trying to understand "graphics", nor
"itools" from which graphics is derived. Studying the *.pro files as
distributed in \lib\graphics and \lib\itools directories would be
enough, in principle. I acknowledge Exelis to have made this software
entirely open.
But such a hacking task cannot be reasonably requested from a
"normal" (and paying) user. Exelis should have produced a decent
documentation too, with a precise description of the adopted
conventions as well as the used principles. Only such a documentation
would make any user really able to understand and efficiently use by
himself the rich capabilities offered by the IDL object graphics. This
lack of documentation is a pity: while IDL might be one of the best
existing multipurpose scientific software, there is the risk that a
growing number of IDL users only "sub-use" IDL (and then question the
licence cost) or, even, leave IDL completely out (e.g. the "python"
effect, etc...).
