Hi Stephan, Thomas,
To preload the png-plugin:
osgDB::Registry::instance()-loadLibrary(png); // or osgdb_png, not

Or I find it easier to do:
osgDB::Registry::instance()-loadPluginForExtension(png);

Hello Simon,

dramatically, which isn't very acceptable.

So why are the manipulators currently set up the way they are? and would the

Ops, it's actually called CameraManipulator... but I've been thinking of
it as a matrix manipulator. Anyway the suggestion is still valid.
It was called MatrixManipulator until recently. That may be why you were

But the point is that the thing that makes it
Hi Tom,
although I'd hope that anyone writing a CameraManipulator would implement both

Well yes obviously. But generally getMatrix() can just be written as

changes that were made.
That's almost right - getInverseMatrix() is the method that's called by
