[Massinissa Bandou]

Hi David,

The target image is rotated by 180 degree about z axis and I'm pretty sure
my landmarks are good (good correspondence) (left:source , right: target)

the source landmark position are:
0.302001   -29.2697   41.482 
-25.2965   14.6525   41.4774 
25.2423   15.2744   41.5059 

the target landmark position are:
0   -29.3294   -41.4782 
25.2489   14.3426   -41.4376 
-25.0866   14.8326   -41.5087 


And the result matrix of transformation is:
-0.999991   -0.00409515   0.000851576   0.102267
-0.00409486   0.999992   0.000332456   -0.28392
-0.000852927   0.000328966   -1   0.01357817
0         0          0         1
