The horizontal swath size should be the product of block height, viewport width, and bytes per element, but the calculation uses viewport height instead of width. The vertical swath size is similarly incorrectly calculated. The effect of this is that we report the wrong DCC caps. [How] Use viewport width in the horizontal swath size calculation and viewport height in the vertical swath size calculation.
