For sure,
In fact, my first idea was exactly the one proposed by Peppe. Then, I 
thought
1) it be may be a bit tricky to include AffineTransform smoothly into 
warping panel with constraints on the number of vectors and good explanation
2) it may be a bit confusing as even with 3 vectors or less, warping do 
not give the same result as affine transform
That's why I just proposed to improve AffineTransform to make it usable 
even by people who do not know warping tool
At the moment, both tools are in the Warp submenu

You're certainly right about warp meaning. The quick search I did about 
it gave me a french word having a wider meaning (deformer = deforming 
?), but I agree that putting AffineTransform inside "Warp" submenu may 
be confusing for english users.
On the other hand, at the moment, there is one AffineTransform is in the 
Warp menu and a New Affine Transformation in the editing menu, which, I 
think, is even more confusing (hum, in fact I already put the "New 
Affine Transform" in the Warp menu)
What do you think about changing the term Warp of the submenu into 
another more appropriate word, and include "Warping", "Affine Transform 
from vectors", AffineTransform from parameters" into it ?
