+Ultrastar Deluxe Hook List
+-----------------------------------
+Here you can find the Events the Core offers to you:
+
+--------------------
+Core:
+--------------------
+Core/LoadingFinished <- Hook is called after all Modules and Plugins are loaded completely, before MainLoop
+Core/MainLoop        <- Hook is called once in MainLoop before Drawing
+Core/Translate       <- Hook is called when Strings should be translated. If this is Retranslating lParam is Non Zero
+Core/LoadTextures    <- Hook is called when Textures should be Loaded. This will be called in Ogl Thread. If Textures are Reloaded (e.g. on Display ReInit) LParam is non Zero.
+Core/ExitQuery       <- Hook is called if someone querys an exit. (e.g. X is pressed). Not called on ForcedExit. If Chain is breaked the exit will be aborted.
+Core/Exit            <- Hook is called before Module a. Plugin unload.
+Core/NewDebugInfo    <- Hook is called everytime there is Debug Info to Output(only if Debug Mode is enabled). wParam: Pchar(Message), lParam: PChar(Reportername)
+Core/NewError        <- Hook is called everytime an error is reported. wParam: Pchar(Message), lParam: PChar(Reportername)
+
+--------------------
+Display
+--------------------
+Display/onScreenChange <-Hook is called when there is an attemp to change Screen. wParam is address to Screens Name(Null Terminated). If Chain is breaked Screenchange will be aborted.
