[fdo-internals] OGR provider...

[Jason Birch]

Hi all,

I've been able to use the OSGeo4W gdal16-* libraries to add MrSID and
ECW capabilities to the GDAL provider (I'll document this in a bit):

http://download.osgeo.org/osgeo4w/release/

and I believe that a similar mechanism could be used to add Oracle / SDE
Raster support.  All of the GDAL/OGR packages available in OSGeo4W and
the notes on each are available here:

http://trac.osgeo.org/osgeo4w/wiki/PackageListing#a1.6.x

That got me thinking about the OGR provider.  If it is using 1.6 and
works with these plugins (is not statically linked?) users could use the
OSGeo4W gdal dll and plugins to get whatever combination of drivers they
wanted.

It's a bit messy because all of the dependencies are dynamic (I had to
add a bunch of DLLs like tiff, geotiff, zlib, etc for MrSID support) but
it's certainly better than being stuck with whatever our project decides
to support.
