private class GlobalStatus from AIS inherits TShared from MMgt

	---Purpose: Stores  information  about objects in graphic context:
	--          - Status Of Display : in the main viewer 
	--                                in the  collector
	--                                fully Erased
	--          - Displayed Modes 
	--          - Active Selection Modes
	--          - is the Interactive Object Current ?
	--          - Layer Index
