41 * In tiled mode, the stride is defined as the distance between the start of the
42 * end line of the current tile and the start of the first line in the next
45 * Tiles are represented in row-major order, thus the end line of current tile
46 * starts at: 31 * 32 (31 lines of 32 cols), the next vertical tile starts at:
47 * 32-bit-aligned-width * 32 and the distance is:
48 * 32 * (32-bit-aligned-width - 31).
