Returns nonzero if the nth
pixel in in1 and in2 uses the pixel
in out without corrupting the (n+1)th pixel of out, (for example, planar<->chunky fails while chunky<->chunky does not); else returns zero.

Generates a new Xform from xformSeq
supplied. Connects numXforms transforms supplied in a KcsXformSeq and returns a KcsXform in newXform that has the same effect as the list of Xforms in the order
supplied. An error in connecting from techs[n]
to techs[n+1] is reflected in errors[n]. A NULL KcsXform is
returned on error.
