Using PascalCase for geometry enum values

This adds a bit more inconsistency to the library, but we didn't have complete consistency before.  Almost all existing string enum values are lowercase (a couple are camelCase and one is dash-separated).  The closure library isn't consistent either (with case for enum properties or values).  I imagine this could be justified in saying someone could blindly use GeoJSON type values in places, but in the end, you'll need to read the docs before guessing right.
