program illustrating the issue
The attached program illustrates the regression. It prints out the raw_values and (transformed) valuator.values reported for XI_RawMotion mouse movement events.
On xserver 1.10, the raw_values and valuator.values are the same (on my system, at least), ie both are relative, which makes sense because my mouse is a relative device.
On xserver 1.11, the raw_values are relative but the valuator.values are absolute.
