Various pointer update schemes. The problem is pointer
motion can cause rapid changes on the screen, e.g. a
window drag. Neither x11vnc nor the bandwidth to the
vncviewers can keep up these rapid screen changes:
everything bogs down when dragging or scrolling.
Note that most video h/w is optimized for writing, not
reading (a 50X rate difference is possible) and x11vnc
is reading all the time. So a scheme has to be used to
"eat" much of that pointer input before re-polling the
screen. n can be 1 to 4. n=1 was the original scheme
used to about Jan 2004. n=2 is an improved scheme.
n=3 is basically a dynamic \fB-nodragging\fR mode: it detects
if the mouse drag motion has paused and refreshes
the display. n=4 is TBD. The default n is 2.

n=1 was the original scheme used to about Jan 2004: it
basically just skips \fB-input_skip\fR pointer events before
repolling the screen. n=2 is an improved scheme:
by watching the current rate it tries to detect if
it should try to "eat" more pointer events. n=3 is
basically a dynamic \fB-nodragging\fR mode: it detects if the
mouse drag motion has paused and refreshes the display.
n=4 is TBD, it will try measure screen read and client
write rates and try to insert "frames" between the
on/off states of mode 3. The default n is 2.

\fB-sync\fR
.IP
By default \fB-remote\fR commands are run asynchronously, that
is, the request is posted and the program immediately
exits. Use \fB-sync\fR to have the program wait for an
acknowledgement from the x11vnc server that command
was processed. On the other hand \fB-query\fR requests are
always processed synchronously because they have wait
for the result.
.IP
Also note that if both \fB-remote\fR and \fB-query\fR requests are
supplied on the command line, the \fB-remote\fR is processed
first (synchronously: no need for \fB-sync),\fR and then
the \fB-query\fR request is processed in the normal way.
This allows for a reliable way to see if the \fB-remote\fR
command was processed by querying for any new settings.
Note however that there is timeout of a few seconds so
if the x11vnc takes longer than that to process the
requests the requestor will think that a failure has
taken place.
.PP
\fB-noremote\fR

Do not process any remote control commands or queries.
