I'm not a fan of Hungarian notation, but C++ kind of needs it with its implicit `this`. And of all the common options for this, I find suffixing members with an underscore the least offensive one.

/**
|
|
* This is only needed to...proxy a connection point proxy. Most hosts will
|
|
* connect a plugin's processor and controller directly using
|
|
* `IConnectionPoint::connect()`. But some hosts, like Ardour, will place a
|
|
* proxy object between them that forwards calls to
|
|
* `IConnectionPoint::notify()`. When objects are connected directly by the host
|
|
* we can also connect them directly in the Wine plugin host, but when the host
|
|
* uses proxies we'll also have to go through that proxy. The purpose of this
|
|
* class is to provide a proxy for such a connection proxy. So when the plugin
|
|
* calls `notify()` on an object of this class, then we will forward that call
|
|
* to the `IConnectionPoint` proxy provided by the host, which will then in turn
|
|
* call `IConnectionPoint::notify()` on the other object and we'll then forward
|
|
* that message again to them Wine plugin host.
