DESCRIPTION
A TrueType collection is a collection of TrueType fonts in one file in which tables may be shared between different directories. In order to support this, the TTC introduces the concept of a table being shared by different TrueType fonts. This begs the question of what should happen to the ' PARENT' property of a particular table. It is made to point to the first directory object which refers to it. It is therefore up to the application to sort out any confusion. Confusion only occurs if shared tables require access to non-shared tables. This should not happen since the shared tables are dealing with glyph information only and the private tables are dealing with encoding and glyph identification. Thus the general direction is from identification to glyph and not the other way around (at least not without knowledge of the particular context).INSTANCE VARIABLES
