Original issue's description:
> Fix dst bound reported by SkTileImageFilter
> 
> In the example from the bug we had the filter DAG:
> 
> color filter (table)
>     0: xfermode filter (arith)
>         0: tile filter [0,80,34,114] -> [0,80,800,480]
>              0: color filter (table)
>                  0: bitmap src 34x34 -> [0,80,34,114]
>         1: color filter (table)
>              0: picture filter [0, 80, 800, 480]
> 
> computeFastBounds was coming out of the DAG with a bound of [0,80,34,114] which didn't represent the pixels that would be drawn.
> 
> This CL updates SkTileImageFilter to correctly set the bound for the pixels it will hit.
