Updated model pitch handling to match current GZDoom implementation. Fixed imprecise vertex coordinates generated by Draw Ellipse mode. Fixed a resource loading exception when opened map file wad was located in the root of a Directory resource. Internal: changed output of all InterpolationTools methods from int to float. Fixed, Internal: InterpolationTools.InterpolateColor() delta usage was inverted.
