D237: F10 overlay category headers (DISPLAY/VIEW/MOUSE/CONTROLLER/GAME) + SkipIntro, Show FPS, pad invert/deadzone/trigger rows

New non-selectable ROW_HEADER kind: navigation, wheel and clicks step over
headers. Wheel scroll already existed. Port-only; Win + Linux builds clean;
overlay capture verified.

Live-verified Surface 1/2 + Depot; awaiting user play-test sign-off.** Historical trail — pass 24 (2026-09-21, static) DECODED THE TREE TEXTURE** (new `tools_pc/texdecode.py` ports image.c's LOOKUP/HUFFLOOKUP/RLELOOKUP codecs). **`tex1198` LOD 0 = 64×17 RGBA5551, 44.2% opaque, and its 1-bit alpha renders as an unmistakable treeline silhouette** — pass 23's identification confirmed by decode, not inference. **Rare authored a six-level LOD pyramid that PRESERVES the silhouette and its alpha coverage (44.2% → 43.1% → 38.8%), each level a separately-authored image with its own compmethod.** Since `XLU_SURF` has no alpha test (pass 22), averaging that 0/1 alpha into fractional mip alpha would smear the minified treeline into exactly the reported band — so 'authored LOD chain replaced by driver-generated mips' is now the leading mechanism, with hard ground truth behind it. Corrects pass 23: only `tex1198` is a treeline (`tex1199` 89.4% opaque denser foliage; `tex1200`/`tex1201` 100% opaque detail textures sharing the class). Two decoder bugs found while porting (missing per-image byte-align, `image.c:1096`; a GUESSED rather than ported RLE fudge) — both produced confident wrong pictures. **Pass 25 (live) answered all three questions: (1) YES 64×17 RGBA16 intact, pool ≡ offline decode; (2) YES alpha survives (44.2% opaque); (3) NO — no code path uploads authored chains as GL mips.** New: `tex1198`–`1201` are **never drawn from an idle spawn** (zero RGBA16 imports in 4800 frames) — the spawn wall is painted by other classes (cf D276/D280); the drawn tree-class card is **`tex149` IA8 32×64 hard cutout, byte-exact import, no authored chain**. Mip mechanism located: `texGetDepthAndSize` sizes LOADBLOCKs from the header `lods` field even for single-image textures (live A/B: 2808 B vs 2048 B real data), and the port's RC2 clip + `glGenerateMipmap`/trilinear (observed live) box-filters hard 0/F alpha into fractional mips → XLU smear. Pass 26 fix directions in entry (cheapest: no mip gen for no-chain textures). |

 ## D238 — QoL ask (M-106, user QA): mouse sensitivity rework toward normal PC-shooter feel.
 
 **QoL ask (M-106, user QA): mouse sensitivity rework toward normal PC-shooter feel.** Three parts: (1) a *separate* RMB aim-mode sensitivity in addition to hipfire turn; (2) ideally ONE single master mouse-sensitivity setting driving both, **linked by default**, with an option to set them independently later (today `Input.MouseAimSpeed` and `Input.MouseTurnSpeed` are two independent keys, defaults 16/100 — see `input.c:188-190`); (3) up/down should feel mostly the same as left/right (`Input.MouseYScale` exists but the axis asymmetry in the gain constants `AIM_GAIN`/`MOUSE_TURN_GAIN` + smoothing path is the likely culprit). User's reference for "feels better": GEPD Mouse Injector. Lump with the overall mouse/input fixes (D194/D165/D166 lineage; SOLITAIRE natural-pitch scheme switch may subsume part of this — see D166 M-87 note).
