//! leptonica-morph - Morphological operations for image processing
//!
//! This crate provides morphological operations including:
//!
//! - Structuring elements (SEL) for defining operation neighborhoods
//! - Binary morphology: erosion, dilation, opening, closing
//! - DWA (Destination Word Accumulation): High-speed morphology using word-aligned operations
//! - Grayscale morphology: erosion, dilation, opening, closing for 8-bpp images
//! - Color morphology: erosion, dilation, opening, closing for 32-bpp images
//! - Hit-miss transform for pattern detection
//! - Morphological gradient, top-hat, and bottom-hat transforms
//! - Connectivity-preserving thinning (skeletonization)
//! - Morphological sequence operations for chaining multiple operations
