3D-Transform / Perspective

[jomo]

It would be really nice to change an image's perspective, similar to this feature in GIMP:

The function could look like this:

img.transform([x, y], [x, y], [x, y], [x, y], function(err, image) {
  // do stuff
}

Where each [x, y] is the new position of a corner inside the current image.

Or:

img.transform(a, b, c, d, e, f, function(err, image) {
  // do stuff
}

• 3D-Projection
• Affine transformation

• I believe this is the code used by GIMP
• There are a lot of implementations when you search around
