Add Optix render window

The RenderWindow class works by attaching to an existing GUI window using its ID / window ?at=default&fileviewer=file-view-default#RenderTarget.hh-105 handle string . This currently works for ogre as it already has built-in ?at=default&fileviewer=file-view-default render window support . The ?at=default&fileviewer=file-view-default OptixRenderWindow class is currently just a stub and doesn't do anything.

For optix, we currently require the user to save the image data a buffer in memory then display it into their own window (e.g. see ?at=default&fileviewer=file-view-default#GlutWindow.cc-95 this line in simple_demo that captures data into image data object example) which requires users to write more code.

It would be nice to have a common RenderWindow API that masks these differences.
