Details:

In the developement veresion of image package, the following code should
return 1 :

A = [1, 2, 0; 3, 4, 0; 5, 6, 1];
T = maketform ('affine', A);
all (all (T.tdata.T == A))


maketform actually stores A in T.tdata.Tinv. I have attached a changeset that
fixes this behaviours and makes subsequent changes in cp2tform.m
