Rendering fixes for e-ink displays:
- Remove backing bitmap (was 1/4 resolution, caused blurry strokes)
- Draw strokes directly as paths for pixel-perfect rendering
- Disable anti-aliasing on stroke and grid paint (no edge fading)
- Grid: darker color (rgb 180,180,180), 2pt stroke width for crispness
New features:
- Line snap: hold pen still for 1.5s to snap to straight line from origin
- Box tool: draw rectangles by dragging corner to corner
