python question - change position of event-msgs

I've already modified a lot of the MainInterface and also added the GreatPersonBar by Impaler, but now my problem is that the messages(events) shown in the top-center of the screen each turn (finished units, buildings and so on) are to close to the GreatPersonBar (imo) and I cannot move the GPBar and ResearchBar more to top as already done... so I like to move these messages 10 to 20 pix more to bottom, but cannot find it in the python-code

does anybody know where resp. how to modify the location these messages are shown?
