+#### Geometry Enhancements
+- **Unified Point System**: New tuple literal syntax for point construction
+  - Simplified API: `Point(2, f32)` instead of `Point2d(f32)`
+  - Consistent interface across all dimensions
+
+#### Canvas Improvements
+- **Bounds Management**: Improved clipping and bounds checking
