Initialize OGRE compositors in SetCamera() instead of Update() so the compositor order can be better controlled. Signed-off-by: Steve Peters <scpeters@openrobotics.org>

I think you should be able move this check to the top of the function as we don't need to set the params anymore

There are several
SensorPlugins that create Ogre compositors (such as LensFlareSensorPlugin). It was reported by @mogumbo that the order in which compositors are applied affects the rendered output, but theLensFlareSensorPluginalways seems to be applied last, regardless of the order in which plugins are specified in an SDFormat file. @iche033 suggested moving the code for initializing agazebo::rendering::LensFlarecompositor fromLensFlare::UpdatetoLensflare::SetCamera, so that the compositor would be added during plugin initialization.The initialization code expects a pointer to a
DirectionalLight, which is not available until the first render update. It seems to work to initialize with anullptrfor theDirectionalLightsince the light ptr is being set every update. I also added logic to exitnotifyMaterialRenderearly if the light pointer isnullptr.
