        STCProxy

Proxy object to defer requests to a real STC.

Used to wrap a real STC but supply some custom methods. This is used in the case where the major mode is using a real stc for its data storage, but not using the stc for display. Because the major mode depends on an stc interface to manage the user interface (enabling/disabling buttons, menu items, etc.), a mode that doesn't use the stc for display still has to present an stc interface for this purpose. So, wrapping the buffer's stc in this object and reassigning methods as appropriate for the display is the way to go.
