Added BitmapOptions, which allows games to adjust the scale of image.

This allows an app to configure BitmapFactory.Options.inSampleSize to
downsample an image while decoding it, and then adjust the scale factor of the
image to match so that the image behaves exactly the same in their app, but
uses 1/4th the memory (and of course looks less awesome, but if it's that or
your app doesn't run at all, maybe visual degradation ain't so bad).
