Region Mask

[Pixelcon]

An automatically added RE that gives a simple black and white mask of the render region would be quite useful I think.

Can you describe the workflow you are aiming with this?

If I do a region render, comping the new render over the old can be a pain in very specific situations if for example I'm using bucket mode and I cancel before it has completed the entire region.

Basically it means I could stack my region renders over the old render and use the mask I am describing as a mask in PS.
