/** @file negative-bounds.c
 *
 * 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.
