- Could distort a loaded picture (like Photoshop's "liquify", "smudge" or "displacement map").
- Doesn't mess up the use of surfaces and blending-modes in the process.
Alternatively: It could also be an extension that just gave me some really fast equivalent for draw_point and get_point_rgb (no, I'm not gonna look up the correct name); then I could use my own algorithms for reading and redrawing the image using some specific modifications.
I've looked a bit around the forums with no luck, but maybe I just have no idea where to start looking.. However - Thank you so much in advance, if you happen to know of just the thing I'm looking for
