NAME
       glCopyColorSubTable - respecify a portion of a color table

C SPECIFICATION
       void glCopyColorSubTable(GLenum target, GLsizei start, GLint x, GLint y, GLsizei width);

PARAMETERS
       target
	   Must be one of GL_COLOR_TABLE, GL_POST_CONVOLUTION_COLOR_TABLE, or
	   GL_POST_COLOR_MATRIX_COLOR_TABLE.

       start
	   The starting index of the portion of the color table to be replaced.

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

       width
	   The number of table entries to replace.

DESCRIPTION
       glCopyColorSubTable is used to respecify a contiguous portion of a color table previously
       defined using glColorTable(). The pixels copied from the framebuffer replace the portion
       of the existing table from indices start to start + x - 1, inclusive. This region may not
       include any entries outside the range of the color table, as was originally specified. It
       is not an error to specify a subtexture with width of 0, but such a specification has no
       effect.

NOTES
       glCopyColorSubTable is present only if ARB_imaging is returned when glGetString() is
       called with an argument of GL_EXTENSIONS.

ERRORS
       GL_INVALID_VALUE is generated if target is not a previously defined color table.

       GL_INVALID_VALUE is generated if target is not one of the allowable values.

       GL_INVALID_VALUE is generated if start + x > width.

       GL_INVALID_OPERATION is generated if glCopyColorSubTable is executed between the execution
       of glBegin() and the corresponding execution of glEnd().
