I am glad you started to work on the VRT dataset. I think this dataset/driver is the most powerful
of them all. And so useful!
I hope you will also implement the VRTWarpedRasterBand soon as it's the crucial step to make the
OpenEV's reprojection tool work decently...

While you're at it, will you also include info about the other VRTSources? Only when I looked at
vrtdataset.h did I learn that there was a "VRTAveragedSource" which was the answer to the
downsampling question I asked a few months ago (remember the comparisons between gdalwarp and PSP?).
I also noticed there was a "VRTAverageFilteredSource" but I didn't see an implementation of that...

That would be great!
Thanks for your attention.
