ISlideComputer abstracts batched directional-distance computation so GPU implementations can process all slide offsets in a single kernel launch. GpuSlideComputer uses ILGPU with prepared edge data (precomputed inverse deltas and min/max bounds) and caches stationary/moving buffers across calls. GpuEvaluatorFactory exposes a singleton factory method. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
