Changeset 5427 for data/media/gui/scripts/loadGUI.lua

Message:

CEGUI code structure is now set. Images are loaded into imagesets(XML), those are loaded via schemes(XML), which are loaded in lua scripts. Each gui should now be able to be loaded via a seperate lua-script which itself loads its own layout(XML).
