Image_PixMap has been extended to support definition of 3D bitmap (as an array of 2D slices). Graphic3d_TypeOfTexture enumeration values have been renamed to include full enum prefix. Added Graphic3d_TypeOfTexture_3D redirecting to GL_TEXTURE_3D. OpenGl_Texture::Init() has been extended to allow initialization of 3D texture. Graphic3d_Texture2Dmanual merged into Graphic3d_Texture2D and marked as deprecated alias. Graphic3d_TOT_2D_MIPMAP has been deprecated in favor of dedicated Graphic3d_TextureRoot::SetMipMaps(). Added Graphic3d_Texture3D class. vtexture - added argument -3d for uploading 3D texture.
