-// Represents a JavaScript object Var. By itself, this represents random
-// NPObjects that a given plugin (identified by the resource's module) wants to
-// reference. If two different modules reference the same NPObject (like the
-// "window" object), then there will be different NPObjectVar's (and hence
-// PP_Var IDs) for each module. This allows us to track all references owned by
-// a given module and free them when the plugin exits independently of other
-// plugins that may be running at the same time.
