// L4PLASMAWIN -- the desktop plasma display (BT_GLASS only).
//
// PlasmaWindow renders the pod's 128x32 serial plasma marquee (pilot-name /
// rank display) into a small orange-on-black desktop window instead of a
// serial device.  It derives from Video8BitBuffered exactly like the serial
// PlasmaDisplay, so the L4GaugeRenderer draws into its 8-bit pixelBuffer
// with the same code path; Update() (the per-frame external-display flush)
// blits the buffer to the window at L4PLASMASCALE x zoom (default 4).
// Selected with L4PLASMA=SCREEN (the gated branch in L4GREND.cpp); any
// other L4PLASMA value keeps the serial device.
