I would like the texture to fit the quad. I have the wes' texcoordmagic stuff but, even with different texmap I don't achieve this when I move the quad by click and drag in the window.

Any idea how can I have the whole texture following the quad when moving?

So the question is How to control the texture coordinates as you can do with [jit.gl.mesh].

Is there an example somewhere that shows how to work with the mouse with tex_plane_s and t messages or any other way to fit the texture to the quad args.

You should have a look at the command list.
