translucent items

Put the summary of the bug you're having here

What I expected to happen was...:
when use resource pack it should work as described

What actually happened was...:
texture pack renders so that the edges of items are transparent

Steps to Reproduce:
1. Best seen on Flow's HD 64x
2. what I have read is that it's not just the texture pack, but the coding that the program
3. Now what appears to be happening can be best described on this link

4. However, this has only occurred from 1.8.1 and on and the extra white pixels on the edge of the item in the png file items seemed to not have affected the textures in the past.: istead of using the white and translucent pixels to on the edge of the item to create a 3d shape, it just rendered them as it was and did not affect the overall quality, unless you really looked for it. So this is a bug.

if could help that would be great thanks!
