/**

 * Compute the dimensions to use for a given sampleSize.

 *

 * Although AImageDecoder can scale to an arbitrary target size (see

 * {@link AImageDecoder_setTargetSize}), some sizes may be more efficient than

 * others. This computes the most efficient target size to use to reach a

 * particular sampleSize.

 *

 * @param sampleSize A subsampling rate of the original image. Must be greater

 *                   than or equal to 1. A sampleSize of 2 means to skip every

 *                   other pixel/line, resulting in a width and height that are

 *                   1/2 of the original dimensions, with 1/4 the number of

 *                   pixels.

 * @param width Out parameter for the width sampled by sampleSize, and rounded

 *              direction that the decoder can do most efficiently.

 * @param height Out parameter for the height sampled by sampleSize, and rounded

 *               direction that the decoder can do most efficiently.

 * @return ANDROID_IMAGE_DECODER result code.
