/**
* 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.
