High resolution resource pack items such as pickaxes, shovels, blaze rods, and swords do not appear three dimensional. Only the actual texture would appear, not the sides

What I expected to happen was for there to be a whole sword after I used block.

What actually happened was that parts of the three dimensional item were missing or partially transparent

Steps to Reproduce:
1. Load up Minecraft with a high resolution resource pack (IE: Lb Photo Realism, Misa's Pack, Etc.)
2. Get any item that is not a block. (Swords, and bows are affected the most)
3. Press block with the sword or shoot the bow. (Sometimes this step is unnecessary.)
4. You should notice that the side of the sword is now missing/transparent.

Attached is how a diamond sword looked in 1.7.10 versus how it looks in the snapshots.
