Pull Request Overview
This PR adds experimental SIMD-accelerated versions of bitmap difference calculations to improve performance. The implementation introduces SIMD4-based operations for calculating pixel differences, replacing scalar arithmetic operations in the bitmap comparison functions.
- Adds experimental SIMD-accelerated variants of
differenceFullanddifferencePartialmethods - Introduces
rgbaAsSIMD4Int32helper method for SIMD pixel data access - Changes
differencePartialmethod visibility from internal to public
