[osg-submissions] [osg-users] eventState problem in CompositeViewer

[Robert Osfield]

Hi J-S,

I'm currently getting read to test your changes to CompositeViewer,
but first I need to reproduce the error, so in this quest have merged
your changes to osgpick.cpp, and rather than use #ifdef
COMPOSITE_VIEWER have gone for a runtime check using the
--CompositeViewer command line option to switch between the two
viewers.

This works fine, but... so far I haven't reproduced the picking bug.
I only have a single display and GPU attached to my machine right now
so only a single screen.  Is it when running dual screen that problems
occur?

I have checked in the modified osgpick example, to run it with
CompositeViewer simply run:

  osgpick --CompositeViewer cow.osg

Once I can reproduce the bug I'll get on properly review your changes.
 Could you test the above to see if you can reproduce the problem.

Robert.
