/**
 * PluginModuleParent
 *
 * This class implements the NPP API from the perspective of the rest
 * of Gecko, forwarding NPP calls along to the child process that is
 * actually running the plugin.
 *
 * This class /also/ implements a version of the NPN API, because the
 * child process needs to make these calls back into Gecko proper.
 * This class is responsible for "actually" making those function calls.
 *
 * If a plugin is running, there will always be one PluginModuleParent for it in
 * the chrome process. In addition, any content process using the plugin will
 * have its own PluginModuleParent. The subclasses PluginModuleChromeParent and
 * PluginModuleContentParent implement functionality that is specific to one
 * case or the other.
