Hello Yeti and Shi Choong, even though I left science, I still read from time to time the gwyddion mailing-list. I am still curious how this project develops. Yeti, before I left my lab/office in 2015 I send the sources of this drift correction module to you via e-mail. Maybe you still store it somewhere. As far as I remember you had no time or energy to implement/adopt the code. We also had a discussion in terms of different coding styles or unknown potential issues when implementing. However, it seems that this module is really worth implementing. It runs out of the box and so far it did not show any memory leaks. Not only me but many students and collegues of mine worked efficiently with this software. Maybe you should give it a try to implement it as a permanent module. Since AFM images often deal with irregular patterns this might be a useful tool.
