[sharing + question] Send to Syphon and jit.window at different sizes / aspects

    Below is a MAX6 example patch for Syphon noobs like me. It demonstrates how to mix with videoplanes and send out the results as a Syphon stream at an arbitrary frame size, while also rendering to a jit.window at a different size or aspect ratio. (I need this because I'd like to send a stable Syphon stream even if I change my jit.window size and aspect ratio, sometimes adding pillarbox/letterbox to the jit.window without messing up my Syphon output. The key is jit.gl.node)
    The patch works great but there is an issue: (MAX 6.0.5, Syphon beta 2 r2, OS 10.6.8) If I toggle fullscreen on my jit.window, the Syphon stream is momentarily interrupted. Vade responded on the Syphon forum (http://v002.info/forums/topic/2-jitter-syphon-server-issues-upside-down-fullscreen-glitch/) that Jitter destroys and rebuilds the render context so there's nothing they can do. Does anybody know some Jitter voodoo that might preserve the context while going fullscreen? Thanks.

      you can use the @rect message to resize your jit.window without rebuilding the context.

      Of course! Thanks so much. Here's a version that allows fullscreen switching without killing the Syphon stream. (There is a pause of a few frames during switching, but Syphon Recorder keeps rolling without complaint.)
