ConnectionDrawer class
Handles the drawing of connection lines between nearby particles in a network
This class implements an optimized approach to:
- Find particle pairs within connection distance
- Calculate connection line opacity based on distance
- Render visually pleasing connections between particles
Optimization Features:
- Uses spatial grid for O(1) neighbor lookups
- Implements pair processing tracking to avoid duplicate draws
- Caches distance calculations
- Batched line drawing operations
