- 10 year anniversary update
  - Lighting model reworked. moved to eyespace like openGL. [Specular Highlights, Fog, Sphere/Reflection Map] 
  - increased internal s4DVertex to support 4 Textures and 4 Colors [switchable]
  - Textures are handled as sRGB during Mipmap Generation. More accurate, less visual disruption
  - 2D is drawn as 3D like hardware drivers. [switchable]. enables viewport scaling, material2D
  - Texture Spatial Resolution Limiting working. [lower memory consumption,SOFTWARE_DRIVER_2_TEXTURE_MAXSIZE]
  - SuperTuxKart 8.0.1 playable
