Detailed Description

Texture object state.

Contains the array of mipmap images, border color, wrap modes, filter modes, shadow/texcompare state, and the per-texture color palette.

Data Fields
_glthread_Mutex	Mutex
	for thread safety
GLint	RefCount
	reference count
GLuint	Name
	the user-visible texture object ID
GLenum	Target
	GL_TEXTURE_1D, GL_TEXTURE_2D, etc.
GLfloat	Priority
	in [0,1]
GLfloat	BorderColor [4]
	unclamped
GLenum	WrapS
	S-axis texture image wrap mode.
GLenum	WrapT
	T-axis texture image wrap mode.
GLenum	WrapR
	R-axis texture image wrap mode.
GLenum	MinFilter
	minification filter
GLenum	MagFilter
	magnification filter
GLfloat	MinLod
	min lambda, OpenGL 1.2
GLfloat	MaxLod
	max lambda, OpenGL 1.2
GLfloat	LodBias
	OpenGL 1.4.
GLint	BaseLevel
	min mipmap level, OpenGL 1.2
GLint	MaxLevel
	max mipmap level, OpenGL 1.2
GLfloat	MaxAnisotropy
	GL_EXT_texture_filter_anisotropic.
GLenum	CompareMode
	GL_ARB_shadow.
GLenum	CompareFunc
	GL_ARB_shadow.
GLfloat	CompareFailValue
	GL_ARB_shadow_ambient.
GLenum	DepthMode
	GL_ARB_depth_texture.
GLint	_MaxLevel
	actual max mipmap level (q in the spec)
GLfloat	_MaxLambda
	= _MaxLevel - BaseLevel (q - b in spec)
GLint	CropRect [4]
	GL_OES_draw_texture.
GLenum	Swizzle [4]
	GL_EXT_texture_swizzle.
GLuint	_Swizzle
	same as Swizzle, but SWIZZLE_* format
GLboolean	GenerateMipmap
	GL_SGIS_generate_mipmap.
GLboolean	_Complete
	Is texture object complete?
GLboolean	_RenderToTexture
	Any rendering to this texture?
struct gl_texture_image *	Image [MAX_FACES][MAX_TEXTURE_LEVELS]
	Actual texture images, indexed by [cube face] and [mipmap level].
struct gl_color_table	Palette
	GL_EXT_paletted_texture.
For device driver.
Note: instead of attaching driver data to this pointer, it's preferable to instead use this struct as a base class for your own texture object class. Driver->NewTextureObject() can be used to implement the allocation.
void *	DriverData
	Arbitrary device driver data.
