<p>It is gallium nine only for now.</p>
<p>In the case of gallium nine, it as a reasonnable assumption all
accesses to the rendered content (read/write) is done through the
api. Besides the window messages are independent of whether there
is presentation or not (and when). Thus you can delay the
presentation.</p>
<p>I believe in the case of GL, it is too much to do these
assumptions. Though perhaps the option could still be added and
user test if for their app it works or not. But it's not trivial
work to add support for the option.</p>
