Has there been any work to minimize the size and number of dependencies, or modularize it, or produce a "PostGIS-lite"? Usually I'm happy to grab a good library even if it's overkill, but PostGIS pulls in many hundreds of megabytes -- far more than every other library I use combined. I wish there were a way to say "I want the GIS data types, but I don't need JPEG2000 and every other possible image format".
