Python-Fu script to apply light bloom effect on an image. Simply put, this script will make shiny parts of the image even shinier and makes the light creep over the edges of darker objects, sort of like what usually happens when you take a photo against the light. The script will create a flattened copy of the image, and add a layer of light on top of it. You can play with the growth settings in the script and the layer opacity and mode to achieve certain effects. Suggested modes are Soft Light, which creates a very subtle effect, and Hard Light, which creates a stylish, exaggeratedly shiny effect.
