Auto-growing layers

GNU Image Manipulation Program, or GIMP in short, is one of the most popular image editing programs that is Free and Open Source. But currently, the image layers need to be resized manually which is inefficient and degrades user experience. This can be particularly frustrating when using a brush tool. Also, beginners might find it hard to use. So this project aims to add support for Auto growing layers in GIMP and other features required for implementing it.
