Replace the palette-swatch windows with ones that render DOSBox's live gauge
framebuffer -- the M_LIN16 16bpp video memory (vga.mem.linear, 640x480, 5:6:5,
start=vga.config.real_start) via glDrawPixels. Each window now shows the real
gauge image, matching the DOSBox screen ("similar output"), confirmed live.
Diagnostic: the VDB splitter-on log now prints the framebuffer mode
(0x111 / M_LIN16 / 640x480) -- confirming direct color, so the palettes are
not index LUTs.
All three windows currently show the shared framebuffer identically; the
per-display palette decode (how the VDB carves the encoded 16bpp stream into
the six monitor outputs) is the next step.
