Changeset 6003 for code/branches/ingamemenu/data/gui/scripts/InitialiseGUI.lua

Message:

Implemented support for multiple simultaniously showing GUIs. What happens now, in essence, is, that every root-window of a gui, that is to be showed, is attached to a global root window, which is always displayed and therefore needs to be fully transparent (alpha = 0.0). To not inherit the transparency (and thus be fully transparent as well) each root-window of a gui must (or should) set the property 'InheritsAlpha' to false.
