// Per-frame repaint pump (2026-08-04, "indicators flash slowly unless focused").
//
// These windows repaint off a 62 ms WM_TIMER. Windows COALESCES/THROTTLES timer
// AND paint messages for a window that is in the BACKGROUND (not focused) -- so
// when the game window (or another app) holds focus, the panel's WM_TIMER slows
// to a crawl and the lamp FLASH (a repaint-driven animation: BTLampBrightnessOf
// alternates the shade off GetTickCount every paint) drags. Giving the panel
// focus un-throttles its timer, which is exactly what playtesters saw.
//
// Fix: drive the repaint from the MAIN render loop (BTGlassPanels_Tick, called
// once per frame from L4VIDEO), gated to the same ~16 Hz flash cadence. The main
// loop runs every frame while the game is up regardless of which window has focus,
// and InvalidateRect + UpdateWindow forces a SYNCHRONOUS WM_PAINT -- bypassing the
// throttled timer-message path entirely. The WM_TIMER stays (it still owns the
// one-shot re-snap); a focused window just repaints from whichever fires first.
