25  *
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.
