ud-emulator 0.1.3

//! `comctl32.dll` stubs — the common-controls surface.
//!
//! Codecs pull `comctl32` in only for their configuration
//! dialog (themed buttons, sliders). The sandbox never opens
//! that dialog; the single stub just needs to resolve so the
//! codec's CRT init / DllMain completes.
//!
//! Reference: MSDN `comctl32` API.
