I tried it on some 5MP image files and the redraw rate was acceptable. With larger files 10MP+, I'm concerned that the redraw rate might be too slow using GIMP's current process, but this is an assumption on my part based on the processing I assume GIMP must do with layers. What would it take to put any finishing touches on this script and incorporate officially in a future release? Also, would it be possible to add an icon of a camera to the toolbox so that the user doesn't have to access it through the menu structure (similar to Adobe Acrobat)? .....
