Could u explain what the meta information is based on? In order to accomplish an
undo, would this meta information be used to perform the inverse of an
operation?
A situation where I dont think the meta information would make sense
would be: when resizing an image (u

for each action the GIMP undo systems stores all of the image data
that is
