The MOUSE_TRANSFORM flag collects a few mouse positions (default is 4) for
average before creating mouse events (WM_MOUSEMOVE etc.).
I have disabled it with the MOUSE_RAW flag instead.
I think this is a better way to disable filter_transform.
Without filtering the touch is more responsive and sometimes another
prefiltering is done inside of the touch device driver.
But the application should work with MOUSE_TRANSFORM too!
Bye
Uwe
