L<Gtk2::Ex::SyncCall>) so that after drawing one frame the next doesn't go
out until hearing back from the server that it finished the previous.  This
ensures a high frame rate doesn't flood the server with more drawing than it
can keep up with, but instead dynamically caps at client+server capability.

Scroll movements are calculated from elapsed time using
C<clock_gettime(CLOCK_REALTIME)> when available or high-res system time
otherwise (see C<Time::HiRes>).  This means the display moves at the
C<speed> setting even if drawing is not keeping up with the requested
C<frame-rate>.  Slow frame rates can occur on the client side if the main
loop is busy doing other things (or momentarily blocked completely), or can
be on the X server side if it's busy with other drawing etc.
