*
* To make this serializable, we changed this void* pointer into

* buffer.
*
* That buffer is PluginEvent::mBuffer below.
*
* We wrap this in that PluginEvent class providing operators to
* be compatible with existing code that was written around
* the old void* field.
*
* Ideally though, we wouldn't allow arbitrary reinterpret_cast'ing here;
* instead, we would at least store type information here so that
* this class can't be used to reinterpret one structure type into another.
* We can also wonder if it would be possible to properly extend
* WidgetGUIEvent and other Event classes to remove the need for this
* mPluginEvent field.
