A ComfyUI node that takes Width and Height inputs, ensures they are
divisible by 32 (ComfyUI standard), and provides a switch to swap the output order.
The UI step size is fixed at 32 to match ComfyUI's resolution requirements.
Perfect for:
- Resolution validation and adjustment (32-pixel alignment)
- ComfyUI-compatible dimension processing
- Dimension swapping for orientation changes (portrait/landscape)
- VAE encoder/decoder compatible resolutions
