Hi,
you should make a mesh feed by a 3 3 matrix to setcell and make any distortions you want, texturize it, et voilà.
here’s a dirty patch, sorry but I think it does what you want.
Ask if any questions.

i had the feeling i shouldn’t mess with the texcoords but manipulate the mesh matrix instead.
would like to use jit.vexpr to get more precision, but your method is sound. keepin’ it simple

thanks
