 * An enumeration representing the result of a drawing operation.
 *
 * Most users of DrawResult will only be interested in whether the value is
 * SUCCESS or not. The other values are primarily useful for debugging and error
 * handling.
 *
 * SUCCESS: We successfully drew a completely decoded frame of the requested
 * size. Drawing again with FLAG_SYNC_DECODE would not change the result.
 *
 * INCOMPLETE: We successfully drew a frame that was partially decoded. (Note
 * that successfully drawing a partially decoded frame may not actually draw any
 * pixels!) Drawing again with FLAG_SYNC_DECODE would improve the result.
 *
 * WRONG_SIZE: We successfully drew a wrongly-sized frame that had to be scaled.
 * This is only returned if drawing again with FLAG_SYNC_DECODE would improve
 * the result; if the size requested was larger than the intrinsic size of the
 * image, for example, we would generally have to scale whether FLAG_SYNC_DECODE
 * was specified or not, and therefore we would not return WRONG_SIZE.
 *
 * NOT_READY: We failed to draw because no decoded version of the image was
 * available. Drawing again with FLAG_SYNC_DECODE would improve the result.
 * (Though FLAG_SYNC_DECODE will not necessarily work until after the image's
 * load event!)
 *
 * TEMPORARY_ERROR: We failed to draw due to a temporary error. Drawing may
 * succeed at a later time.
 *
 * BAD_IMAGE: We failed to draw because the image has an error. This is a
 * permanent condition.
 *
 * BAD_ARGS: We failed to draw because bad arguments were passed to draw().
