  26  * Tests the following piece of the GL_ARB_copy_buffer spec:
  27  *
  28  *     "An INVALID_VALUE error is generated if any of readoffset,
  29  *      writeoffset, or size are negative, if readoffset+size exceeds
  30  *      the size of the buffer object bound to readtarget, or if
  31  *      writeoffset+size exceeds the size of the buffer object bound
  32  *      to writetarget."
  33  *
  34  * Note that the overlap test, as an example, will make sure that the
  35  * error checking doesn't fail copies within the bounds.
