Doc fix: update BitmapFactory.Options.inSampleSize javadoc

         * pixel in the decoded bitmap. For example, inSampleSize == 4 returns

         * an image that is 1/4 the width/height of the original, and 1/16 the

         * number of pixels. Any value <= 1 is treated the same as 1. Note: the

         * decoder will try to fulfill this request, but the resulting bitmap

         * may have different dimensions that precisely what has been requested.

         * Also, powers of 2 are often faster/easier for the decoder to honor.

         * decoder uses a final value based on powers of 2, any other value will

         * be rounded down to the nearest power of 2.
