/*!
* pixaInsertPix()
*
* Input: pixa
* index (at which pix is to be inserted)
* pixs (new pix to be inserted)
* box (<optional> new box to be inserted)
* Return: 0 if OK, 1 on error
*
* Notes:
* (1) This shifts pixa[i] --> pixa[i + 1] for all i >= index,
* and then inserts at pixa[index].
* (2) To insert at the beginning of the array, set index = 0.
* (3) It should not be used repeatedly on large arrays,
* because the function is O(n).
* (4) To append a pix to a pixa, it's easier to use pixaAddPix().
