Warp Transform (work in progress)

For a long time I wanted to add a warp transform feature. Warping really helps with making more advanced adjustments and allows for fun experiments that can make drawings feel more dynamic. With the updated Select > Transform, now is a good moment to add this feature. So I am currently working on this! My implementation maps the image onto a subdivided mesh which is then deformed according to a grid of control points (https://en.wikipedia.org/wiki/Free-form_deformation). I think that's how it's done in other software as well.

Here is a little preview:

I still have to tackle a number of problems before it can be released. The update should also bring improvements to the regular transform. E.g., I want that you can adjust the transformation by doing a pinching gesture with your fingers.

Stay tuned!
