Add viewport/camera system with pan, zoom, and world-space cursor conversion2026-05-07T08:31:42ZMartin Kagamino Lehouxmartin@lehoux.net2026-05-07T08:31:42Zurn:sha1:b2ca89d8193d98aa21e9637257c3e7a7216b9bd8
- New camera.go: Camera struct with arrow-key pan, scroll-wheel zoom toward
cursor, middle-mouse drag, exponential velocity decay, and world-bounds clamping
- Layout() now returns screen dimensions (960x640) instead of world size so
the camera GeoM transform drives all rendering
- All world entities, halos, text, path lines and spawn target converted via
camera transform in draw.go; banners remain in screen space
- selection.go: separate startScreen field so the drag-select box draws in
screen space while selection logic stays in world space
- Banner heights and font sizes scaled down to fit the 640px logical screen
- Three new integration tests: ScreenToWorld round-trip, bounds clamping,
zoom-toward-cursor stability
