Compose two (or more) images together #222

Hi!

Would it be possible to add a feature to compose (add) two (or more) images together?

Hi, could you describe your envisioned use-case in more detail?

I'm hesitant to add image editing / modification features to tev -- it is meant to be an image comparison tool first and foremost, so any kind of image composition that gets added to it should serve that purpose somehow.

I'm doing a lot of data dumping from the renderers - I separately dump various signals to separate EXRs. For example, I save to disk separately Direct Diffuse Illumination and Direct Specular Illumination signals. Due to various reasons sometimes I can't or don't need to output the full Direct Illumination output and in such cases I'd like to just compose these two EXRs together in tev. It could work as the already implemented feature to do the substraction of two images (IIRC it's called the reference mode).
