Support Bloom #43

Bloom often shows up with HDR. Bloom occurs when really bright areas of the image "bleed over" into darker parts of the image. It can be achieved by blurring the image and then combining the blurred image with the unblurred image. See the end of this presentation.

This can now be implemented as a tone map!

Bloom isn't a tone map; it's just a filter. Tone maps are related to transforming HDR images into [0;1] bounded images.
