NAME
	  glGetTexLevelParameterfv, glGetTexLevelParameteriv - return
	  texture parameter values for a specific level	of detail


     C SPECIFICATION
	  void glGetTexLevelParameterfv( GLenum	target,
					 GLint level,
					 GLenum	pname,
					 GLfloat *params )
	  void glGetTexLevelParameteriv( GLenum	target,
					 GLint level,
					 GLenum	pname,
					 GLint *params )


     PARAMETERS
	  target  Specifies the	symbolic name of the target texture,
		  either GL_TEXTURE_1D,	GL_TEXTURE_2D,
		  GL_PROXY_TEXTURE_1D, or GL_PROXY_TEXTURE_2D.

	  level	  Specifies the	level-of-detail	number of the desired
		  image.  Level	0 is the base image level.  Level n is
		  the nth mipmap reduction image.

	  pname	  Specifies the	symbolic name of a texture parameter.
		  GL_TEXTURE_WIDTH, GL_TEXTURE_HEIGHT,
		  GL_TEXTURE_INTERNAL_FORMAT, GL_TEXTURE_BORDER,
		  GL_TEXTURE_RED_SIZE, GL_TEXTURE_GREEN_SIZE,
		  GL_TEXTURE_BLUE_SIZE,	GL_TEXTURE_ALPHA_SIZE,
		  GL_TEXTURE_LUMINANCE_SIZE, and
		  GL_TEXTURE_INTENSITY_SIZE are	accepted.

	  params  Returns the requested	data.

     DESCRIPTION
	  glGetTexLevelParameter returns in params texture parameter
	  values for a specific	level-of-detail	value, specified as
	  level.  target defines the target texture, either
	  GL_TEXTURE_1D, GL_TEXTURE_2D,	GL_PROXY_TEXTURE_1D, or
	  GL_PROXY_TEXTURE_2D.

	  GL_MAX_TEXTURE_SIZE is not really descriptive	enough.	 It
	  has to report	the largest square texture image that can be
	  accommodated with mipmaps and	borders, but a long skinny
	  texture, or a	texture	without	mipmaps	and borders, may
	  easily fit in	texture	memory.	The proxy targets allow	the
	  user to more accurately query	whether	the GL can accommodate
	  a texture of a given configuration.  If the texture cannot
	  be accommodated, the texture state variables,	which may be
	  queried with glGetTexLevelParameter, are set to 0.  If the
	  texture can be accommodated, the texture state values	will
	  be set as they would be set for a non-proxy target.

	  pname	specifies the texture parameter	whose value or values
	  will be returned.

	  The accepted parameter names are as follows:

	  GL_TEXTURE_WIDTH
		    params returns a single value, the width of	the
		    texture image.  This value includes	the border of
		    the	texture	image. The initial value is 0.

	  GL_TEXTURE_HEIGHT
		    params returns a single value, the height of the
		    texture image.  This value includes	the border of
		    the	texture	image. The initial value is 0.

	  GL_TEXTURE_INTERNAL_FORMAT
		    params returns a single value, the internal	format
		    of the texture image.

	  GL_TEXTURE_BORDER
		    params returns a single value, the width in	pixels
		    of the border of the texture image.	The initial
		    value is 0.

	  GL_TEXTURE_RED_SIZE,

	  GL_TEXTURE_GREEN_SIZE,

	  GL_TEXTURE_BLUE_SIZE,

	  GL_TEXTURE_ALPHA_SIZE,

	  GL_TEXTURE_LUMINANCE_SIZE,

	  GL_TEXTURE_INTENSITY_SIZE
		    The	internal storage resolution of an individual
		    component.	The resolution chosen by the GL	will
		    be a close match for the resolution	requested by
		    the	user with the component	argument of
		    glTexImage1D or glTexImage2D. The initial value is
		    0.

     NOTES
	  If an	error is generated, no change is made to the contents
	  of params.

	  GL_TEXTURE_INTERNAL_FORMAT is	only available if the GL
	  version is 1.1 or greater. In	version	1.0, use
	  GL_TEXTURE_COMPONENTS	instead.

	  GL_PROXY_TEXTURE_1D and GL_PROXY_TEXTURE_2D are only
	  available if the GL version is 1.1 or	greater.

     ERRORS
	  GL_INVALID_ENUM is generated if target or pname is not an
	  accepted value.

	  GL_INVALID_VALUE is generated	if level is less than 0.

	  GL_INVALID_VALUE may be generated if level is	greater	than
	  log  max, where max is the returned value of
	  GL_MAX_TEXTURE_SIZE.

	  GL_INVALID_OPERATION is generated if glGetTexLevelParameter
	  is executed between the execution of glBegin and the
	  corresponding	execution of glEnd.
