- 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 git-svn-id: svn://svn.code.sf.net/p/irrlicht/code/trunk@6086 dfc29bdd-3216-0410-991c-e03cc46cb475
