[gdal-dev] Call for discussion on RFC 70: Guessing output format from output file name extension

[Mark Johnson]

Reading the Magic-Header signatures first and then guessing from the file
extension may be a better approach.

In spatialite gaia_exif.c, the function gaiaGuessBlobType has a collection
of signatures to start with, combined with spatialite.c guess_mime_type
returning the mime type as string.
