[Vv] x and y axes flipped

[Simon Rit]

Hi,
One solution is to change the TransformMatrix. If you want to flip x and y,
then change it to
TransformMatrix = 0 1 0 1 0 0 0 0 1
Regarding VV, only with the git version and the CLITK_EXPERIMENTAL build
option will it display it accurately. But RTK in any case should account
for this transform.
