[PyQt] simulate fluent mouse move trajectory (Peter Irbizon)

[lloyd konneker]

You are asking to move the cursor (a viewed thing), not the mouse, which 
is a pointing device (a control.)

Generally, in a GUI you should not move the cursor except to follow the 
mouse.  If you move the cursor in response to a mouseMoveEvent, it would 
be smooth.

If you really want to move the cursor independently of the mouse, is 
your question about line drawing algorithms, not PyQt?
