 Well, I believe I've completed the functions for FV.01.  The following
 functions have been added:

 ST_Band(rast raster, bandnums int[])

 ST_AsGDALRaster(rast raster, format text, options text[], srs text)

 ST_AsTiff(rast raster, options text[], srs text)

 ST_AsPNG(rast raster, options text[], srs text)

 ST_AsJPEG(rast raster, options text[], srs text)

 Each of the above have several variations.

 I've also added two ancillary function:

 ST_getGDALDrivers()
   for getting available and usable GDAL drivers on the server

 ST_srtext(rast raster)
   A bunch of the functions needed to get a spatial reference's
 srtext/proj4text to pass to the GDAL raster, so this function was written.

 I've added test cases to both test/core and test/regress though I think
 the test cases could be built upon.

 As my C skills were definitely rusty when I started this, please feel free
 to correct my errors and more importantly, let me know what they are.  I
 will admit, the code was easy to understand and well documented!

 Oh, I did make one tweak to raster/scripts/python/Makefile.in to accept
 the variable DESTDIR for when building packages.
