[mono-android] Image Banding

[Tomasz Cielecki]

I recently ported a ColorPicker where I had a similar issue. I show
this ColorPicker which is a custom view in a Dialog. Inside this
Dialog, which is also a custom Dialog I simply wrote:

     Window.SetFormat(Format.Rgba8888);

In the constructor, this helps me avoiding banding entirely.
