doc: Intuition Screens — comprehensive rewrite with Copper mechanics, input routing, hazards
- Copper connection: how the coprocessor enables multi-resolution screen
coexistence via scanline-synchronized register switching, with cross-links
to Copper articles (08_graphics, 01_hardware)
- Display modes: OCS/ECS/AGA/RTG chipset generations, native resolution
table (PAL/NTSC × LoRes/HiRes/SuperHires × interlaced), special modes
(HAM, HAM-8, EHB), Display ID system, RTG with CyberGraphX/Picasso96
- Screen dragging: Copper WAIT coordinate manipulation, keyboard shortcuts,
real-world usage patterns (Workbench+game, productivity multi-screen,
video production, public screen sharing)
- Input event routing: input.device handler chain, Intuition consumption
model, IDCMP flag reference table, event behavior during screen drag,
Left-Amiga vs Right-Amiga shortcut convention, cross-screen routing
- Pitfalls: CloseScreen deadlock, IDCMP message leak, layer lock deadlock,
screen pointer invalidation, interlace flicker, MOUSEMOVE flooding,
hardcoded Display IDs — all with WRONG/RIGHT code examples
- Expanded best practices (10 items), SA_ tag reference, overscan modes,
public screen lifecycle, DrawInfo querying, BestModeID() usage
