Porting over to 2.1 I found in plugin and standalone-demo that calling 'new' (SimpleGraph.Clear) after using merge gives an accessviolation. Also trying to delete the component (SimpleGraph.Free) after using merge gives an accessviolation.
I have added:
FEO_SETFONTSTRIKEOUT = 25;
FEO_RESETFONTSTRIKEOUT = 26;
for use in 'ForEachCallback'.
