From Stephan Hunber, "attached you’ll find some changes to osg/p3d:

* a new command-line-option to present3d and a new option to the p3d-plugin to suppress any found <env> tags
* a new command-line-option to present3d to forward mouse-events via osgGA::Device (defaults to off) so we can test the interface-files with present3d better
* I added a new attribute forward_to_devices for click_to_event to forward the event to all attached devices instead of handling the event locally. This will fix the annoyance with the new interface-files when toggling polygon-mode or switching light on/off.

Here’s an example:

<click_to_event forward_to_devices="true">0x72</click_to_event>
