 I have to admit I really love this new feature.  One thing that would make
 this even nicer is if it can render more complex types such as
 Curved geometries, TINS, and PolyhedralSurfaces.  I presume this is more
 of a GDAL enhancement than a PostGIS change.  Am I correct in assuming
 that it's pure GDAL and a possibly newer library in the future may be able
 to just work with an upgrade of GDAL library.

 Which brings me to the second question of how far away is GDAL from being
 able to do this.  I know for example MapServer in 6.0 now supports
 rendering of PostGIS curves (though haven't tested), but not sure if that
 is built into mapserver (I presume it is).

 BTW started putting pictures in doc for raster.  I'm just putting them in
 for now instead of having them rendered, I have a small ASP.NET app I'm
 building to demonstrate these functions which I'll share later as a
 tutorial.
