[android-developers] Re: Why dither a bitmap

If you're loading a very large bitmap and you want to show it on a
phone with small heap space e.g. 16MB or 24MB, you may want to change
the bitmap to 16 bit, RGB_565.

Then you'll realize that gradients look stair-stepped. So when you
enable dithering, it breaks the obvious stair-steps and makes it look
like a smoother gradient.
