- * occupying unique byte addresses and with consistent byte offsets between
- * neighboring pixels.
- *
- * The FlexLayout structure is used with any pixel format that can be
- * represented by it, such as:
- *  - PixelFormat::YCBCR_*_888
- *  - PixelFormat::FLEX_RGB*_888
- *  - PixelFormat::RGB[AX]_888[8],BGRA_8888,RGB_888

- *  - even implementation defined formats that can be represented by
- *    the structures
- *
- * Vertical increment (aka. row increment or stride) describes the distance in
- * bytes from the first pixel of one row to the first pixel of the next row
- * (below) for the component plane. This can be negative.
- *
- * Horizontal increment (aka. column or pixel increment) describes the distance
- * in bytes from one pixel to the next pixel (to the right) on the same row for
- * the component plane. This can be negative.
- *
- * Each plane can be subsampled either vertically or horizontally by
- * a power-of-two factor.
- *
- * The bit-depth of each component can be arbitrary, as long as the pixels are
- * laid out on whole bytes, in native byte-order, using the most significant
- * bits of each unit.
+ * A buffer descriptor is an implementation-defined opaque data returned by
+ * createDescriptor. It describes the properties of a buffer and is consumed
