Part of #1205.

(#24) SDL window improvements:
- image clipboard (BMP / PNG by MIME);
- cursor scaling for HiDPI;
- Wayland-aware window flash;
- colour cursors.
Do this after the Game Control branch merges; both touch llwindowsdl.cpp.
(#1) Their extensions on top of LL's LLGameControl (which #1202 / #1203 / #1204 bring in):
- per-mode tuning;
- gyro and trackpad (Steam Controller);
- controller-to-key and gesture bindings;
- flycam;
- the preferences UI with controller diagrams.
Their Steam Controller support needs SDL features from their custom 3.4.18 build: bump our own 3p-sdl3 instead.

Credit in code comments and in the About / release notes. The per-feature evaluation (local) is in research/GUNMETAL_DX_2026-10-28.md; the section 3 table numbers are quoted as (#n).

For every stage:

Port by hand onto current dev. Their base is 44+ commits behind, and the renderer files have moved on.
Strip their settings down to the few that earn a place (minimal config space). Experiment toggles are Persist=0.
Never take their custom SDL3 build (SDL3-3.4.18-gmdx1), updater, crash reporter, installer or branding.
