Does Documentation for GlideOverlay exist? They don't seem to exist on docs.servicenow.com.

var o = new GlideOverlay({
            title : "Edit Metadata Request",
            iframe : metadataservice_gui_url,
            allowOverflowX : true,
            height : 650,
            width : 1000
            //messages : ""
        });

Preferences/settings were set by passing an object.

I'm interested in knowing what other settings can be passed?

I'd specifically like to know if this overlay window can be made resizable?

Thanks
