STIXE interface pack
From TrillWiki
Interface packs change how STIXE based skins display their interface. (i.e. they control the layout of the skin.) This is where the real code for how a STIXE skin looks resides.
While, in theory, a non-STIXE skin could link into this shared codebase, in essence this would make that skin a STIXE skin (or a hybrid).
