Ports from a downstream fork, hand-surgered hunk-by-hunk to exclude the
fork's randomizer/pokescript work and to skip a FixedStep jitter-tolerance
attempt that never fixed the stutter it targeted.
- src/core/Timing.lua: hardware-accurate frame-delay catalog ported from
pret/pokered, feeding BattleState:waitNext, EffectRegistry's miss/crit
beats, TextBox/ChoiceBox scroll and prompt holds, and the battle
silhouette slide/shake/blink/faint timings.
- Seamless battle transitions: Renderer:drawBattleWipe replaces the old
160x144-only cascade with one wipe drawn over the whole surface at any
zoom or window size; BattleTransition's per-style frame lengths are
corrected against pokered-c's derivation; Transition.battleReturn adds
the post-battle GBFadeInFromWhite the port never had.
- BATTLE SIZE / BATTLE BG options (BattleState:wantsFillScale/bgMode,
Game.fillScaleInStack/worldBgBattleDim): battle surface can fill the
window instead of the fixed integer letterbox, and the area around it
can show white/black/the dimmed overworld instead of only white.
- src/core/FaithfulRes.lua: locks the window to an exact 160x144 multiple.
- Zoom-aware UI anchoring: Renderer:uiScale steps the UI down with survey
zoom (gated to worldActive so the title/intro never shrink);
Renderer:setUIAnchor lets TextBox, ChoiceBox, and an opted-in Menu
(the START menu) pin themselves to a screen edge instead of the
zoomed-out letterbox.
