Better WriteableBitmap implementation
I need to write to a bitmap which is very painful (imagine a vnc client for example) on windows phone right now, so please support the Copy- and WritePixels methods and some others.
Do you know about the WriteableBitmapEx library? It's in NuGet now. http://wpdevelopers.ginktage.com/2011/05/17/writeablebitmapex-goes-nuget/
