Here's an example usage:

void GetAwesomeness(InfoObject &obj) {
obj.DefineProperty("awesome", mAwesome);
}
int mAwesome;
GfxInfoCollector<Foo> mInfoCollector;

This will define a property on the object
returned from calling getInfo() on a
GfxInfo object. e.g.
gfxInfo = Cc["@mozilla.org/gfx/info;1"].getService(Ci.nsIGfxInfo);
info = gfxInfo.getInfo();
if (info.awesome)
alert(info.awesome);
