* Add alpha pass output, to use set Transparent option in Film panel. * Add Holdout closure (OSL terminology), this is like the Sky option in the internal renderer, objects with this closure show the background / zero alpha. * Add option to use Gaussian instead of Box pixel filter in the UI. * Remove camera response curves for now, they don't really belong here in the pipeline, should be moved to compositor. * Output full float values for rendering now, previously was only byte precision. * Add a patch from Thomas to get a preview passes option, but still disabled because it isn't quite working right yet. * CUDA: don't compile shader graph evaluation inline. * Convert tabs to spaces in python files.
