The RP412 single-window cockpit, adapted to reuse BT's working D3D
surface compositor (DrawDevSurface) instead of RP's GDI child-window
panes -- same visual outcome, far lower risk (no L4VIDEO present-routing
rewrite):
- L4VB16.cpp: kBTCockpitSurfaces places the six instrument surfaces at
RP412's exact 1920x1080 fractional positions (Heat=UL, Mfd2=UC,
Comm=UR, Mfd1=LL, Mfd3=LR, radar=center-bottom portrait);
BTDrawGaugeSurfaces parameterized by surface table; BTDrawCockpitPanel
composites them over the full-window 3D as the pod bezels frame the
viewscreen. Hooked in L4VIDEO before EndScene (L4MFDSPLIT-gated).
- btl4main.cpp: L4MFDSPLIT sizes the window to the 1920x1080 canvas
(scaled to fit the work area; -res overrides) and wakes the gauge
renderer (L4GAUGE) + PAD controls.
Fixed two more pre-existing latent gauge crashes that only fire when the
gauge renderer is woken off-pod (would hit the real pod too), previously
gated only on BT_DEV_GAUGES -- extended the safety nets to L4MFDSPLIT:
* gauge.h: NULL gauge-attribute-source binds a static zero instead of
AV'ing in GaugeConnectionDirectOf ctor (crashed building HeatSink
cluster's VertTwoPartBar at ConfigureForModel).
* GAUGE.cpp: SEH-guarded gauge Execute (disable a faulting gauge, not
crash). GAUGREND.cpp: skip unresolved primitives + activate all MFD
pages so every surface renders.
Verified: L4MFDSPLIT boots the cockpit; all six surfaces render framing
the 3D viewscreen; survives coolant-loop + gauge activation.
