See the answer I've just posted, but there's no evidence that Andrea is running
into the performance problems related to wrapped VRT. The VRTs produced by
gdalbuildvrt have no rotation. gdalbuildvrt only accepts "north-up" tiles. I'll
rather suspect a performance problem due to accessing ECW through VRT.
