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