# The zori UI consists of several "pages" or screens of UI.
# Only one page can be active at the same time, and the size fo a page is 
# that of the screen.
# The page named :default is normally active and is supposed to be used 
# for the in-engine UI and HUD elements, dialogs, etc.
# Other pages are for screens such as the start screen, save screen,
# main menu, inventory, etc.
