[Vv] Affine transform

[Simon Rit]

Dear vv users,
I put back the affine transform code that we had disabled a few months
ago for memory consumption reasons. This is still experimental but we
have planned to test and validate it tomorrow with David and Romulo.
If I were you, I would not update until the end of this week (except
if you want to be a pre-alpha tester)... We will send you more
information as soon as we have reached a satisfactory status. There
will however be a release pretty soon.
Thanks,
Simon
