I have a few questions pertaining to Graphics within Unidraw. Any
help/pointers will be much appreciated:

i) Can someone out there list the RULES FOR USING TRANSFORMERS
   (the Transformations processor) in InterViews. Browsing through
   the literature and the man pages, I drew a blank. Stepping through
   some code and dumping out data structure values unravelled part of
   the mystery, but is turning out to be an extremely tedious process.

ii) Can I abstract the graphic state representation of InterViews to
    a normalized and succinct representation in terms of a

	- a chosen number of fonts, brushes and a perspective, and

	- co-oridnates with respect to an absolute frame of reference

    With this normailized representation I want to recreate a replica of
    the graphic (same scaling, translation, rotation and perspective)

iii) I am having trouble with initializing the HANDLER for a component
     derived from GraphicComp. This is the sequence of operations 
     I perform 

	- obtain the original coordinates of the views graphic, 

	- apply the graphic's total transformation to these
	  coordinates

	- initialize a rubberhandle with the transformed co-ordinates

    This does not work! What I get are rubber handles that are translated
    to the left and to the bottom and these *do not change* when the graphic
    is zoomed into.


Thanks in advance.
