New Revision: 7602

Modified:
   trunk/gs/doc/pscet_status.txt
Log:
Provide the CPSI compatibility for Type1 subglyph placement.

DETAILS :

Debugged with CET 16-01-1 16-02-1 16-10-1 16-10-2.

The new 'seac' offset formula 'overall_x_offset'
has been empirically derived from placements of
the "round" accent subglyph in the CPSI rendering. 

EXPECTED DIFFERENCES :

None.
