I'm doubtful that this PEP alone would allow zero-copy sharing of images
for display. Often, the libraries need the data in a different format.
So they need to copy, even if they could understand the other format.
However, the PEP won't allow "understanding" the format. If I know I
have an array of 4-byte values: which of them is R, G, B, and A?
