SND\AstrorEnales_cp 0fc4409e58 - Fixed the Texture2DReader to correctly fill the texture with the mipmaps
- Implemented Mipmap textures for Dx10, Dx11, GL3. Metro is implemented but has still some problems with mipmaps (probably cause of the vm)
- Added Sample dds texture
- Fixed compiler error in MetroGameTimer
