Listen on RawEvents: listen for raw events on the root
window and decide whether the cursor is shown or not. A
touch begin event will hide the cursor a motion or button
press event will show it.
There is no API in XFixes to know whether a cursor is shown
or not so we keep track of the current state. Furthermore
we trap X errors if any bad access should happen.
