docs: Add comprehensive API coverage analysis
Tested all 43 major SDL3 APIs:
- 15/43 (35%) fully working with zero errors
- 28/43 (65%) partial with 1-13 errors each
- 0/43 (0%) failed
Production Ready APIs (15):
✅ Input: keyboard, scancode, mouse, touch, pen
✅ Core: cpuinfo, sensor, time, process, locale, version, power
✅ Graphics: rect, blendmode
✅ Other: keycode
Near-Perfect (20 APIs with just 1 error):
⚠️ audio, camera, clipboard, error, events, filesystem,
gamepad, gpu, guid, haptic, hidapi, init, iostream,
joystick, log, messagebox, mutex, pixels, render,
storage, surface, thread, tray
Key Findings:
- Function pointer typedefs block 23 APIs (HIGH priority)
- Keyword field names affect 3 APIs (MEDIUM priority)
- Edge cases affect 2 APIs (LOW priority)
Impact:
- ~5 hours effort → 91% coverage (39/43 APIs)
- ~8 hours total → 100% coverage
See API_COVERAGE.md for detailed breakdown.
