Border textures.

[JackOnTheMap]

I'm stumped and while I do have a bit of knowledge of oUF setups, I just can not figure this one out. It's probably something so simple I'll facepalm but what the heck.

I'm using a UF that has a glowTex that is making the borders more than particularly fuzzy.
What I really want it a nice, sharp 1px (or 2px) border and for the life of me, I haven't been able to find a texture that will replace the one that the frame is using.
I've taken other textures and renamed them to "glowTex". Changed paths. Nothing I'm trying is working.

Thank you for your time.
