With the introduction of flowing liquids on June 15th, the prior flowing water animation gained a new augmentation where the texture would be shifted a certain amount to give it a proper flowing appearance.
I do not know how much this translation actually is, though.
There are probably two versions of this animation: one 16x16 version, for its 20100615 debut, and a 32x32 version, to accommodate the rotation and other transformations 20100616-1808 onwards did for flowing fluids.
As the flowing water texture very likely used RNG for generation, it may vary between sessions and getting a loopable animation may not be possible.
