[mapguide-users] Adding OpenLayers.Layer to Fusion Map

[Zac Spitzer]

your going to need to dive into the whole projection and OL spherical
mercator stuff

I'm prety sure the google layers will be added as what's called a base
layer in OL which means
they won't be displayed by default

does the layer switcher show up?
