Comment:

 This is because the image is warped when it is loaded and considered a
 'warped virtual dataset'. The image being drawn is not the original base
 image, though we do still have a pointer to that base image.

 It seems like pyramids could be build for the based image, and then
 reloaded and rewarped again, but I need to check with the GDAL folks to
 see if pyramids are supported at all with virtual datasets.
