Set background filler color on Windows Phone 8

[fre...@casualgames.nu]

Dear All,

I've implemented Admob ads into my Windows Phone 8 game and so far it works nice.

However I do have a problem and that is that the background color of the "filler" color is always set to white. Even if I set the color to something else in the .XAML file, it overrides it to white. 

I think that this is a bug in the SDK.

I'm using v6.5.11.0.
