I knew of this configuration possibilities but I still looking for the
right function to use/code for indenting.

Actually, indent-relative would be even better it seems. I think the
way to do it would be, without using AucTeX indenting:
* newline-and-indent followed by indent-relative to split a long line
  starting by \draw or any other command with a backlash, storing
  the value of the column where the beginning backlash is
* newline-and-indent for the next splits for lines not ending with a
  semicolon
* indent back to the value stored after a newline following a semicolon

I'm not sure how i would go about coding this, my lisp skills are
definitely not up to it.
