[SharpDX] BREAKING CHANGES: Remove of DrawingPoint/F, DrawingRectangle/F. Rename of DrawingSize/F to Size2/F, and DrawingPoint to Point. DrawingPointF is now Vector2. Constructor of Rectangle/F are taking (X, Y, WIDTH, HEIGHT) instead of (left, top, right, bottom). Add several missing helper methods in Rectangle/F (Intersects, Union)
