This now works.  I can't tell if it's using the Vivante - the display is
pretty slow...

Also, I get continuous errors/warnings running the demo:
    QWSLock::down(): Invalid argument
    QWSLock::up(): Invalid argument
    QWSLock::up(): Invalid argument
    QWSLock::down(): Invalid argument
        ...

Any ideas about this?

Thanks
