Re: [vwnc] Aragon widgets need updating - was RE:Re-2:DragAndDropwith datasets

The correction may well only be needed for the post-primitive code. We
had problems caused by that code in another case, and our fix is part of
AR51018. Here's my version comment, and the fix is attached - perhaps
Christian could test that it solves the Aragon problem without needing
his override?

* Fix for bug in VW which causes the whole of any text containing even a
single 2-byte character to be not displayed unless near the top left of
the screen. Such characters are roughly those not in Unicode 0-255, so
this doesn't affect most European languages, but does affect texts
containing Japanese and Microsoft smart quotes. The latter are the most
common cause, e.g. if text is pasted from an MS program.
  - bug is in post-primitive code in
ScreenGraphicsContext>>primDisplayCharacterOfIndex:at:, introduced in
7.3.1. Reported to Cincom as 388361: TwoByteString not displaying for
Float co-ordinate. Confirmed and created as AR 51018.

Yes it does. Thanks - this is a proper solution.

Cheers,
