[gdal-dev] GDAL formats list order

[Ivan Lucena]

Hi Jorge

"Arbitrariness is a term given to choices and actions 
subject to individual will, judgment or preference, based 
solely upon an individual's opinion or discretion."  
Wikipedia

That's sounds about right.

There are several different cases and reason for a driver 
be moved up or down on that list. For example, if a 
format is not safely identified, if it doesn't have a MIME 
header, and if we have cases where it catches somebody 
else files, we move it down on the list.

http://trac.osgeo.org/gdal/wiki/GDAL20Changes that 
GDAL formats, when calling gdalinfo --formats, "are 
returned in a meaningful order - the order they are tried - 
which is important to know sometimes".

gdalallregister.cpp several calls to GDALRegister_X, in 
what looks like an arbitrary order to me. Seems to have 
"groups". Apart from that, older drivers first?
