Issue with cast method to convert between coordinate systems

bug.md

Following the instructions for converting points between different coordinate systems posted on http://daniel-azuma.com/articles/georails/part-4, I tried:

require 'rgeo'
require 'pp'

north_wa_proj4 = '+proj=lcc +lat_1=48.73333333333333 +lat_2=47.5 +lat_0=47 +lon_0=-120.8333333333333 +x_0=500000.0001016001 +y_0=0 +ellps=GRS80 +datum=NAD83 +to_meter=0.3048006096012192 +no_defs'

north_wa_factory = RGeo::Cartesian.factory(:srid => 2285,
:proj4 => north_wa_proj4, :coord_sys => north_wa_wkt)

wgs84_factory = RGeo::Geographic.spherical_factory(:srid => 4326,
:proj4 => wgs84_proj4, :coord_sys => wgs84_wkt)

space_needle = north_wa_factory.point(1266457.58, 230052.50)
space_needle_latlon = RGeo::Feature.cast(space_needle,
:factory => wgs84_factory, :project => true)

p "Original, Projected:", space_needle, space_needle_latlon
p "Expected:", wgs84_factory.point(-122.34978, 47.620578)

When I ran $ ruby test.rb , I got:

"Original, Projected:"
