Improve zoom smoothness, add absolute position cache (#21)
* Improve trackpad pinch-zoom smoothness
- Replace Math.pow(0.99, delta) with Math.exp(-delta/100) zoom curve
for natural, symmetric scaling that handles both tiny trackpad deltas
and large mouse wheel jumps gracefully
- Normalize wheel deltaMode (LINE → 40px, PAGE → 800px) so external
mice on Firefox produce consistent zoom behavior
- Clamp per-flush scale factor to 0.75–1.25 to prevent jarring jumps
from discrete mouse wheel ticks
* Add per-frame absolute position cache for SceneGraph
