     PARAMETERS
	  target	  Specifies the	target texture.	 Must be
			  GL_TEXTURE_1D.

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

	  internalFormat  Specifies the	internal format	of the
			  texture.  Must be one	of the following
			  symbolic constants:  GL_ALPHA, GL_ALPHA4,
			  GL_ALPHA8, GL_ALPHA12, GL_ALPHA16,
			  GL_LUMINANCE,	GL_LUMINANCE4, GL_LUMINANCE8,
			  GL_LUMINANCE12, GL_LUMINANCE16,

			  GL_LUMINANCE6_ALPHA2,	GL_LUMINANCE8_ALPHA8,
			  GL_LUMINANCE12_ALPHA4,
			  GL_LUMINANCE12_ALPHA12,
			  GL_LUMINANCE16_ALPHA16, GL_INTENSITY,
			  GL_INTENSITY4, GL_INTENSITY8,
			  GL_INTENSITY12, GL_INTENSITY16, GL_RGB,
			  GL_R3_G3_B2, GL_RGB4,	GL_RGB5, GL_RGB8,
			  GL_RGB10, GL_RGB12, GL_RGB16,	GL_RGBA,
			  GL_RGBA2, GL_RGBA4, GL_RGB5_A1, GL_RGBA8,
			  GL_RGB10_A2, GL_RGBA12, or GL_RGBA16.

	  x, y		  Specify the window coordinates of the	left
			  corner of the	row of pixels to be copied.

	  width		  Specifies the	width of the texture image.
			  Must be 0 or 2**n + 2*border for some
			  integer n.  The height of the	texture	image
			  is 1.

	  border	  Specifies the	width of the border.  Must be
			  either 0 or 1.

     DESCRIPTION

	  fglCopyTexImage1D defines a one-dimensional texture image
	  with pixels from the current GL_READ_BUFFER.

	  The screen-aligned pixel row with left corner	at (x,y) and
	  with a length	of width + 2 * border defines the texture
	  array	at the mipmap level specified by level.
	  internalFormat specifies the internal	format of the texture
	  array.

	  The pixels in	the row	are processed exactly as if
	  fglCopyPixels	had been called, but the process stops just
	  before final conversion.  At this point all pixel component
	  values are clamped to	the range [0, 1] and then converted to
	  the texture's	internal format	for storage in the texel
	  array.

	  Pixel	ordering is such that lower x screen coordinates
	  correspond to	lower texture coordinates.

	  If any of the	pixels within the specified row	of the current
	  GL_READ_BUFFER are outside the window	associated with	the
	  current rendering context, then the values obtained for
	  those	pixels are undefined.

     NOTES
	  fglCopyTexImage1D is available only if the GL	version	is 1.1
	  or greater.

	  Texturing has	no effect in color index mode.

	  1, 2,	3, and 4 are not accepted values for internalFormat.

	  An image with	0 width	indicates a NULL texture.

     ERRORS
	  GL_INVALID_ENUM is generated if target is not	one of the
	  allowable values.

	  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_VALUE is generated	if internalFormat is not an
	  allowable value.

	  GL_INVALID_VALUE is generated	if width is less than 0	or
	  greater than 2 + GL_MAX_TEXTURE_SIZE,	or if it cannot	be
	  represented as 2**n +	2 * (border) for some integer value of
	  n.

	  GL_INVALID_VALUE is generated	if border is not 0 or 1.

	  GL_INVALID_OPERATION is generated if fglCopyTexImage1D is
	  executed between the execution of fglBegin and the
	  corresponding	execution of fglEnd.
