|

// A state buffer is a dynamic container for data passed from
|
|
// the engine thread to the UI thread. It may be used for
|
|
// holding window content, in which case it will have an HWND
|
|
// associated with it, or it can be an internal buffer for non-UI
|
|
// purposes.
|
|
//
|
|
// A list of current window-associated state buffers is kept for
|
|
// the engine to traverse when it is updating state for the UI.
|
|
// The UI thread is the only thread that can add to this list.
|
|
// The engine thread is the only thread that can remove a buffer
|
|
// from the list. This is necessary for proper lifetime management
|
|
// of dynamically-created buffers.
