Mouse pointer calibration

```
What steps will reproduce the problem?
1. Set Scaling mode to "1:1" and Input Mode to "Mouse Pointer Control Mode"
2. Use touch screen to move mouse pointer.
3. Mouse pointer consistently appears some way below the screen tap
location. For example, if Firefox window is open and maximized, to focus on
the location bar one has to tap at the very top of the screen where the
window bar (top border) is. It is not possible to access the Firefox menu
or the close/restore/minimize buttons in the window bar itself.

What is the expected output? What do you see instead?
Mouse pointer should appear in the same place as screen was tapped.

What version of the product are you using? On what operating system?
0.3.0 (latest version from Archos AppsLib) on Archos 5 Internet Tablet with
firmware 1.3.07 (Android 1.5).

Please provide any additional information below.
This is a AndroidVNC specific problem, not observed in other applications
on Archos 5 Internet Tablet.
