Subject: [PATCH] winex11.drv: Send relative RawMotion events unprocessed.

This makes relative raw input independent from cursor speed, as it is
the case on Windows. Absolute raw input is already translated to
virtual desktop space, and cursor speed is meaningless in this case.

This does not support mixed relative/absolute X/Y axis.
