// L4GLASSWIN -- per-display glass cockpit windows (BT_GLASS only; this TU is
// only in the build when the gate is on -- see CMakeLists.txt).
//
// Under `-platform glass` with BT_GLASS_PANELS=1 (the glass preset default),
// each pod SECONDARY display gets its OWN desktop window carrying that
// display's surface AND its RIO button bank placed AROUND it, mirroring the
// physical pod cockpit:
//
//   Heat (UL) / Mfd2 (UC) / Comm (UR) / Mfd1 (LL) / Mfd3 (LR)  -- red MFD
//        banks split 4 buttons ABOVE / 4 BELOW the surface;
//   sec radar (center, portrait)                               -- yellow
//        Secondary buttons split LEFT / RIGHT of the surface;
//   Flight Controls                                            -- the
//        no-display banks (throttle 0x38-3F, joystick/fire 0x40-47, panic).
//
// Each window is a GDI window (like L4PADPANEL + L4PLASMAWIN): the surface is
// CPU-expanded from the shared gauge pixelBuffer (SVGA16::ExpandPlaneToBGRA)
// and StretchDIBits'd in -- NO D3D, so the whole D3D dev-composite path
// (dock / separate window / overlay) stands down while these are up.  Clicks
// inject through PadRIO::SetScreenButton; lamps render from GetLampState.
// Created / destroyed by the PadRIO ctor / dtor.
