[gdal-dev] GPU support for GDAL

[Javier Jimenez Shaw]

The ovr is "just" a tiff with several "pages" (I do not know the exact
name). Like in the old times, using a scanner to scan several pages of a
document. (actually, there are some image viewers that show you this
opening a tiff with embedded overlays: several pages)
You can create that with gdal. Unfortunately I forgot the details.
