Description

I have warped VRT, that translating in different ways depending on the scale. In the absence of overview images of the source everything is ok. Also scaling works fine when I erase GeoTransform info from VRT-file.
Steps to reproduce result:

  1. Unpack attached archive
  2. gdal_translate grid.vrt test_100.tif
  3. gdal_translate -outsize 50% 50% grid.vrt test_50.tif
