Ok, I just tried the .zip version of my 32x texture pack & the animations don't work. The only ones that work are the portal, fire, water, & lava animations. None of the other ones work. I have all the .txt definitions for my animations too, so I didn't mess up. This is a bug that I'm experiencing too.
Ok, I tried the folder version of my 32x texture pack & the animations work fine. I'm about to try it with the .zip version of my 32x texture pack, & see what happens.

There is no 13w09c snapshot at this time.
Now my opinion on Mojang not looking at MCPatcher for inspiration on how to fix things is totally up to the coder/Mojangster who is trying to fix/implement the feature in question. But @misa has a point & plus using @Kahr 's MCPatcher's method of changing width calculations to floats can be a quick fix you guys can do, & then come back later to fix the feature the way you guys(Mojangster) want it to be.
This is just my opinion, & it's totally up to Grum to do this how he wants it to do it, whether that is use MCPatcher's way of doing it or another way, that's totally up to him to decide
