It's a shared memory area generated by a COTS software package. As such, we can't modify its byte-order. There may be multiple copies of this package running at the same time, each with its own "virtual framebuffer". We want to display all of these vfbs on a real display that's running X with the Intel driver. Brute force copying the vfbs using XPutImage() is the only method we've come up with for displaying the vfbs. But that required us to make a copy of the source vfbs with the byte-order fixed. By setting the byte_order field of the _Ximage structure, we hope we can eliminate the intermediate copy of the vfbs.
