API Migration

• Improved Intersection Detection for Landscape Terrain.

We have significantly improved intersection detection for the Landscape Terrain. Along with a set of optimizations the algorithms have changed.

We have improved the algorithm of bicubic filtering with an optimized data reading operations on CPU. Bicubic filtering is now controlled per Landscape Layer Map.

Intersection detection algorithm has become faster and much more accurate. The End Precision value is removed as the updated algorithm now always converges to a finite and accurate solution.

Intersections for rays cast from under the terrain surface are now detected properly. There'll be no false-positive intersection detection for rays cast perpendicularly to the terrain surface and no more false-positives along the edges of layer maps.

All related changes are listed below.
