[Gimp-developer] Huge performance improvement idea

Greetings from Chandana,

I have an idea that can make a huge impact on performance increase on GIMP
image manipulations. This idea occurred to me when I was working on a large
banner which I had to do some experiments (Colour changes, layer movements,
Font changes, etc...)

The problem was, it took so long time to do even a small change in the
image. I do not have huge memory. What I thought was, what if I can
1. Get a copy of the current image (with all layer details)
2. Resize it to a smaller version
3. Do all the modifications I do in the small version
4. Apply all changes I did in the smaller version to the larger version

This way, computer resources required are much less than what needed in the
original image. We need to implement a way so that GIMP will remember all
the modifications we do in the small image and from a single click GIMP
should be able to do it to the larger image. Another good version of this
idea would be to

1. Create a small image
2. Do whatever we want in to the small image
3. From a single click, GIMP create scaled up image and apply all the
things we did to the small image to the large image

Please take this idea into consideration.

Thank you,
