[osg-users] OsgText compile issue with the newer versions of OSG

[Trajce Nikolov NICK]

Hi Robert,

that is part of a code I wrote that has history :-) and now is part of the
OpenIG project. Originally this was written like 6-7 (???) years ago and
was part of the osgWidget::Input too ( I had submission then for this ).
The purpose was to have a Line Edit as is known in any UI. OpenIG is using
it for typing commands as from terminal and here is the whole code
https://github.com/CCSI-CSSI/MuseOpenIG/blob/master/Core-OpenIG/Terminal.cpp
....

This particular snippet Curtis is mentioning was changed over time (simple
changes that are handled with #ifdefs) and now we have the same case - I am
aware of the recent osgText refactors but don't know the details. The
purpose of this snippet is to get the glyphs coords of the edited text in
order to set the cursor position. That simple :-).

The mentioned snippet is using the API for a decade that now become broken,
so I will vote to make it back compatible again - if it will be a simple
addition what I believe it is the case

Please let me know your thoughts and what will be the best effort to fix
this issue

Thanks a bunch as always!

Cheers,
NIck
