My UI and Scaling

[PerfectH]

I was thinking the other day: "What if I could fix my UI so that fit on virtually any resolution?". Judging by the default UI and other UI compilations I have seen (Mazzle, Spartan, etc), it could be done.

I'm just wondering how. I use kgPanels for art and PitBull for unit frames. I have artwork attached to most of my unit frames (including the Minimap). I also use art to add a "button socket" effect for by Bartender 4 action bars, however, they are not attached to the action bars through parenting.

If I scale the UI down right now (I think), change resolution or the aspect ratio, the unit frames jump out of place, as to be expected. Can I fix this so that my UI is a little more universal and more people can use it? If the default UI can support any resolution, why shouldn't mine?
