[Libvncserver-common] SendPointerEvent method

[<luk...@se...>]

Hello,
I would like to ask how exactly SendPointerEvent method works. Lets say I 
want to move cursor to point(0,0). When I try it several times, cursor is 
not moved to only one position. I think it depends on position of cursor 
before calling this method. When I move cursor manually to Point(x,y) in 
some VNC viewer and then I call SendPointerEvent, new position of cursor 
depends on position Point(x,y), why?
I use only libVNCClient to connect and handle Qemu's VNC server , so I cant 
use libVNCServer method like rfbSetCursor to set cursor on default position.
So how can I move cursor for example to the top left corner?
