User: "it doesn't scale with our screen resolution?" -- correct. The
HUD draws into the fixed 800x600 backbuffer and the present stretches
it into the client area: on non-4:3 windows everything distorted
(circles -> ellipses, the bottom tape widened vs the ladder, positions
drifted outward).
- BTGetPresentAspect (L4VIDEO, from gWindowAspect; 4:3 fallback).
- dpl2d x-unit = (bbW/2)/presentAspect (== bbH/2 at 4:3 -- unchanged
there), circles pre-squished in bb space so the stretch restores
round.
- The reticle<->NDC conversions (BTGetAimRay / BTProjectToReticle /
BTProjectHotBox / BTTwistToReticleX) use the PRESENT aspect; the
mouse map (BTClientToReticle) is now pure client-relative.
- Placement itself is authentic and stays put: the binary clusters the
instruments around the boresight (ladder x=0.35 half-heights, spans
+-0.25) -- NOT at the display edges.
- Crash en route: the BTGetPresentAspect extern declared INSIDE dpl2d's
anonymous namespace = a different, unresolved symbol -> /FORCE
garbage call (landed in MissileLauncher::DefaultData). Moved to
global scope; gotcha noted in the comment.
Verified 4:3 regression: aimed lock + zone hits + no crash; hud-geom
MapX/MapY unchanged at 4:3.
