* (4) This works with both stripped and full resolution page models.
* If the full res disparity array(s) are missing, they are remade.
* (5) The caller must handle errors that are returned because there

* (7) This populates the full resolution disparity arrays if

* extension is to the right and down. Nonzero values of (x,y)
* are useful for dewarping when pixs is deliberately undercropped.
* (8) Important: when applying disparity to a number of images,
* after calling this function and saving the resulting pixd,
* you should call dewarpMinimize(dew) on the dew for @pageno.
* This will remove pixs and pixd (or their clones) stored in dew,
* as well as the full resolution disparity arrays. Together,
