Texture Sampling Bleeding

[zicklag]

This is probably not going to be an issue with the renderer rework, but if we want to do a release before the renderer rework is done, then it could be good to fix the bleeding that can be seen for the animated decorations:

I've been plagued by this in my own projects, many a time, but I think it could be somewhat simple to remedy. I've found that reducing the UV along the edges just slightly can keep the sampler from sampling into the next tile and causing the artifacts.
