Code review comment for lp:~vanvugt/mir/fix-1657755

We could communicate both queue length and swapinterval to the server, if we don't want to re-do the client side buffer swapping (which we probably don't).

If the ANativeWindow gets attention in the future, we'd probably want to make a android-specific queue that honors more of the requests the driver can make through the ANativeWindow interface (and then lp: #1369763 could be solved properly).

"As discussed a while back [1], living with LP: #1369763 is probably
the lesser evil. But we should still strive to fix all the bugs."
True, it is probably better to have overlays back.
