Hi,

I had less time than I thought for testing gdalwarping .vrt files.  I have
managed to run gdalwarp at good speed against a .vrt file with 68 GeoTIFF images
(300 MB each).  I do also know that warping .vrt file referring to 200 files in
JPEG2000 format with certain settings is very slow but I have not tested
different JPEG2000 drivers or parameters yet. It would be very interesting to
test the effect of this patch with JPEG2000 images but I am limited to use ready
made Windows32 binaries. I keep my test set-up ready if somebody ever has
gdalwarp binaries including this patch and JPEG2000 support through JP2KAK
driver. We have Kakadu license if it matters.
