//! leptonica-transform - Geometric transformations for Leptonica
//!
//! This crate provides geometric transformation operations including:
//!
//! - Orthogonal rotations (90, 180, 270 degrees)
//! - Horizontal and vertical flips
//! - Scaling (linear interpolation, sampling, area mapping)
//! - Affine transformations (3-point correspondence, matrix-based)
//! - Bilinear transformations (4-point correspondence, nonlinear)
//! - Projective transformations (4-point correspondence, homography)
//! - Shear transformations (horizontal and vertical)
//! - Warping (random harmonic, stereoscopic, horizontal stretch, quadratic shear)
