LD_LIBRARY_PATH so the XUL libs would be found) I noticed that although
the gecko plugin was found it could not be loaded. But this did not
trigger any visible warning/error message (at least not without INFO
notify level). Would you mind if we change the notify level for a
dlerror() to WARNING? This will also make it more explicit for the case
when a plugin isn't actually found, which seems to come up a lot for
novice users (e.g. no freetype on win32, so no freetype plugin, etc).
Also, the current error message is misleading ("Warning: Could not FIND
plugin to ...") because the it's not always a case of not finding the
plugin. I slightly enhanced the situation of not finding a plugin versus
finding it but not being able to load it.
Here's also a few fixes to some of the examples:
- osgfont: make usage help line more in line with the actual behaviour
- osgcompositeviewer: complain when no model file was provided
- osgmovie: don't include quicktime-dependent feature on Linux
- osgocclussionquery: comment addition (as I was surprised that lines
were being drawn in a function called createRandomTriangles())"
