Hello,

Marian,
I mildly dispute this. It is just that you can't express a desire to find
an overview with more than 2 billion pixels in it. The raster itself can
be arbitrarily large. I would claim it is not a common case at all to want
to do random sampling (this function primarily is used by
GDALGetRandomRasterSample()) of more than two billion samples and return it
in a simple array. If you want very dense sampling you should be using some
sort of streaming process.
Best regards,
